Dense phase pneumatic conveying is critically dependent on the physical properties of the materials to be conveyed. However, many materials, such as alumina and coarse fly ash, which are highly abrasive, do not have dense phase conveying capacity. Bypass pneumatic conveying systems provide a dense phase capability to non-dense phase capable bulk materials. These systems also provide the capacity of lower the conveying velocity and therefore lower pipeline wear and lower power consumption occurs. The objectives of this work were to study the energy consumption and wear of bypass pneumatic transport systems. Pneumatic conveying of alumina experiments were carried out in a 79 mm diameter main pipe with a 27 mm inner diameter bypass pipe with orifice plate flute arrangement. High-speed camera visualizations were employed to present flow regimes in a horizontal pipe. The experimental result showed the conveying velocity of bypass system is much lower than that of conventional pipelines; thus, specific energy consumption in the conveying process is reduced. The service life of the bypass line has also been estimated.

It is important to assess the toxic effects posed by soil pollutants toward plants. However, plant toxicology experiments normally involve a considerable amount of manpower, consumables and time. Therefore, the use of metal toxicity prediction models, independent of toxicity tests, is critical. In this study, we investigated the toxicity of different metal ions to wheat using hydroponic experiments. We employed the methods of soft¿hard ion grouping, soft¿hard ligand theory and K (conditional binding constant based on the biotic ligand model principle) in combination with hydroponic experiments to explore the application of quantitative ion character-activity relationships in predicting phytotoxicity. The results showed that the toxicity of the 19 metal ions tested varied significantly, with EC50 ranging from 0.27 µM to 4463.36 µM. The linear regression relationships between the toxicity of these metal ions and their physicochemical properties were poor (R2 = 0.237¿0.331, p < 0.05). These relationships were improved after grouping the metals according to the soft¿hard theory (R2 = 0.527¿0.744 and p < 0.05 for soft ions; R2 = 0.445¿0.743 and p < 0.05 for hard ions). The application of soft¿hard ligand theory, based on the binding affinity of the metals to the ligands, showed poor prediction of the phytotoxicity of metals, with R2 = 0.413 (p = 0.024) for the softness consensus scale (sCon) and R2 = 0.348 (p = 0.218) for the normalized hard ligands scale (HLScale). However, the method of K provided the closest fit in predicting toxicity (R2 = 0.803, p < 0.001). Our results showed that the application of soft¿hard ion grouping and log K can improve prediction of the phytotoxicity of metals relatively well, which can potentially be used for deriving the toxicity of elements with limited toxicity data.

Based on the special streamline profile of the Phocoenoides dalli head, this paper innovatively proposes to transform the NACA 0018 airfoil into a novel airfoil whose leading edge is similar to the streamline profile of the Phocoenoides dalli head, and makes corresponding minor adjustments to this new airfoil according to the dolphin's motion behavior, and eventually obtains three kinds of dolphin head-shaped new airfoils including the Original Dolphin Airfoil, the Smooth Transition Dolphin Airfoil and the Deflected Dolphin Airfoil. Due to different deflection angles, the Deflected Dolphin Airfoil is then subdivided into five different types. The aerodynamic performances of these three dolphin head-shaped new airfoils as well as the NACA 0018 airfoil are simulated by using the SST k-¿ model at Re = 1.6 × 105. The results show that: Compared with the NACA 0018 airfoil, firstly, the aerodynamic performances of three kinds of dolphin head-shaped airfoils are quite different from each other because of the change of the curvature and the radius of the leading edge. Secondly, by comparing the lift and drag coefficients of the Deflected Dolphin Airfoils with five deflection angles, it is speculated that there is an optimal deflection angle for the Deflected Dolphin Airfoil under the conditions of this paper. Eventually, the deflection angle of 24° is found to be the optimal value among these five different deflection angles. The results of this study can provide reference for improving the performance of blade design, such as the rotating mechanical blades, the aeronautical blades, etc.

The wind energy exploitation technique has been developed very quickly in recent years. The vertical axis wind turbine is a hot research domain due to several advantages: low noise, flexible for installation, ease of maintenance, great safety and credibility, etc. The aerodynamic performances of different forms of airfoils including an active deformation airfoil and a fluid-solid coupling passive airfoil with two-dimensional (2D) and three-dimensional (3D) cases have been investigated numerically in this paper. Firstly, the aerodynamic performances of the airfoils with the maximum deformation amplitudes of their cambers which are 3%, 5% and 7% of the chord length have been discussed, respectively, with the angles of attack in the range of 0¿ and 20¿ . Secondly, for the angle of attack set at 18¿, the two-way fluid-solid coupling simulations with the Young¿s Modulus of 1 Mpa and 2 Mpa have also been investigated. Results show that: (1) for the pseudo 3D and real 3D single active deformation airfoil cases, the lift coefficients increase as the maximum deformation amplitudes augment from 3% to 7% of the chord length at the same angle of attack. With the same maximum deformation amplitude, when the angles of attack increase from 0¿ to 20¿, the lift coefficients which increase firstly and then decrease are bigger than that of the original NACA0012 airfoil. When the maximum deformation amplitude of the pseudo 3D airfoil reaches 5% of the chord length, a relatively good aerodynamic performance with better inhibition effect of vortex generation can be obtained. The 3D vortex distribution demonstrates that the deformable airfoil has a better vortex generation controlling effect at the middle cross-section along the spanwise direction than the non-deformable airfoil. (2) From the aspect of fluid-solid coupling, the lift increases and the drag decreases so that the lift to drag ratio has a big improvement when the Young¿s Modulus is equal to 1 Mpa and 2 Mpa. The deformable airfoil can inhibit the generation and the shedding of the surface vortex when the fluid-solid coupling effect is considered.

Based on the self-deforming blade model and the related wind tunnel test platform, the experiments with synchronous deformation and pitch of the blade were carried out to simulate the operating condition of the blade on the vertical axis wind turbine (VAWT). Taking NACA0012 as the reference blade, the unsteady aerodynamic characteristics of the blade deformation at different deformation frequencies and amplitudes were investigated at low Reynolds number of 2.5 × 105. It is found that the maximum lift force of the blade with deformation amplitude of 0.06c is raised by nearly 60% compared with that of the rigid blade. Secondly, by applying the same deceleration frequency, same pitch amplitude and different initial angles of attack to the blade, it is observed that the flow hysteresis phenomena are obviously different from that of applying various synchronous pitch and deformation amplitudes, and the special aerodynamic characteristic curves are obtained. The lift force increases significantly with the rise of deformation amplitude and drag force, while the lift-drag ratio increases in one cycle. The study in this paper proves the applicability of the blade with this deformation law in the VAWT, and provides a reference for its application on the design of VAWT.

In this paper, the geometric models of microfluidics NON-AND and AND-OR droplet logic gate devices are designed, and the operations of NON-AND and AND-OR logic are implemented in the designed models. Based on the color-gradient model (R-K model) of lattice Boltzmann method (LBM), the two-phase flow pattern in microchannel is simulated. Based on the ¿equivalent length method¿, the Laplace resistance at the droplet phase interface and the local resistance at the right-angle bend are equivalent to the additional pipe length required for continuous phase flow in the channel to generate the same on-way resistance increment, and the resistance characteristics when slug flow droplets exist in the microchannel are quantitatively analyzed. The method is further applied to the analysis of the resistance characteristics of the droplet logic gate, and the quantitative explanation of the droplet path-choosing behavior is obtained. Compared with the ¿hydroelectricity analogism method¿, the ¿equivalent length method¿ is more concise and easy to understand. The research results in this paper provide theoretical basis for the design of other forms of droplet logic gate devices.

To study the control effect of the plasma actuator on nozzle separated flow, we use a phenomenological model simulating the effect of plasma excitation to numerically study the suppression effect of dielectric barrier discharge plasma and arc discharge plasma on the nozzle separated flow. The effect of different discharge thermal power densities and discharge positions of arc discharge plasma on the suppression effect is further explored. The results show that the arc discharge plasma has a better effect on suppression of nozzle separated flow. When the arc discharge plasma actuator acts on the upstream of the interaction zone of the shock wave and boundary layer, the suppression effect on the flow separation is the best; when the thermal power density of the arc discharge is small, the generated inducing jet velocity is too small to easily influence the flow field of the separation zone; when the thermal power density of the arc discharge is 8×1010 W/m3, the separation reflux area of the nozzle completely disappears.

The plume of solid rocket motor has the characteristics of high temperature, high speed and intense radiation. The temperature of the plume is an essential parameter of condition and performance.The accurate temperature measurement of the plume of a solid rocket motor is important to provide a valuable reference for understanding the internal combustion condition and the overall performance of the motor. With the development of laser and spectroscopy, the laser spectroscopy technology is gradually applied to the measurement of combustion of solid propellant and plume temperature. Radiation spectroscopy thermometry can realize the non-intrusive and on-line measurement of temperature by measuring the radiation spectrum of flame. It has the advantages of wide temperature measuring range, fast response and high reliability. It can be applied to measure the temperature of the plume of the solid rocket motor. In this paper, the thermometry based on radiation spectroscopy was proposed to measure the temperature of the plume of the solid rocket motor. The measurement system of the radiation spectrum of the plume of the solid rocket motor was built using a 350~1 000 nm fiber spectrometer. Moreover, the spectral response coefficient was calibrated with a standard radiation blackbody furnace. The curve of response coefficient with wavelength was obtained to revise the measured radiation spectrums of the plume. Then the measurement system was applied to ground tests of standard f118 solid rocket motors, the radiation spectrums of the plume of the solid rocket motor, which with a typical 12% aluminum mass content propellant, were measured. The characteristics of radiation spectrums at different working times were analyzed. Furthermore, the graybody assumption was discussed based on the two-color gray judgment principle. The radiation of plume in a 675~745 nm spectral range can be considered as graybody.The maximum relative deviation of emissivity with wavelength was 4.01%, and the corresponding mean-variance was 1.53%. Therefore, the parameters of temperature and emissivity at the different working times were obtained by spectral fitting based on Planck radiation law. The maximum deviation between the temperature measurement and the theoretical thermodynamic calculation is 5.40%. Besides, the relationship between the measurement results and conditions were discussed, the radiation spectrums of the plume of the solid rocket motors with 12%, 15%, and 19% aluminum mass content propellants were measured, and the characteristics of radiation spectrums with different aluminum mass content were discussed. In addition, the influences of aluminum mass content on radiation spectrums, temperature, and emissivity of the plume were analyzed with the measurement results. This research on radiation spectroscopy thermometry of the plume of the solid rocket motor can provide the tool for performance evaluation and formulation optimization of the solid rocket motor. The influences of aluminum mass content of propellant on radiation spectrums, temperature, and emissivity of the plume can provide the experimental data support for reducing the characteristic signal of the plume of the solid rocket motor.

Aiming at the problem of thermal deviation in crossover pass of single tangential boiler, an on-line measurement method of radiation parameters of high temperature coal particles based on radiation spectroscopy was proposed. A measurement system consisting of an optical fiber spectrometer system and a water-cooled structure probe was developed, which was used to measure the radiation parameters of high temperature coal particles in crossover pass of the boiler. The radiation spectra at 500¿1000 nm band on the gas flow side of the final reheaters inlet section of a 660 MW ultra-supercritical boiler were measured by the system. According to Planck's law, the distribution of coal particles temperature, emissivity and other parameters along the section was obtained by fitting parameter method. The results show that the burnout delay of pulverized coal particles caused by the air-stage combustion system and the radiant heat transfer deviation caused by the non-uniform concentration of coal particles are the main causes of the thermal deviation of the final reheaters. Under the condition of increasing yaw angle of SOFA nozzles, the ability of SOFA to alleviate the residual swirling flow is significant, and the temperature distribution of coal particles in the crossover pass is more uniform. However, due to the phenomenon of single-side particles accumulation still exists, the deviation of particles radiation intensity remains large, which cannot effectively reduce the steam temperature deviation in reheaters. Through differentially adjusting the angles of SOFA nozzles in vertical direction and horizontal direction, the phenomenon of single-side coal particles accumulation can be improved, the non-uniform radiation heat transfer of heat exchangers on both sides can be balanced, and the steam temperature deviation in final reheaters can be reduced.

Swirling motions have been proven to improve the thermal performance of short natural draft dry cooling towers by reducing the cold air inflow and increasing the draft speed. However, crosswind influences on the favourable swirl effects have not been investigated. To fill this gap, 3-Dimensional simulations of a short natural draft dry cooling tower are carried out. Three different locations of the swirl generator, with solid body rotation, are compared under windless and crosswind conditions. The results show that, with no wind present, introducing swirling motions right above the heat exchangers is found to be the optimal location for improving around 40% of the reduced thermal performance, which is casued by cold air inflow penetration. On the other hand, as the swirl intensity further increases after the cold air inflow is eliminated, locating it at the tower outlet performs the best on the air draft speed enhancement, and thus further increases approximately 17% of the heat transfer rate at the angular frequency input of 2s-1. In the presence of crosswind and windbreak walls, air flows through the heat exchangers and tower non-uniformly. By mounting the swirl generator right above the heat exchangers, the uniform index of the heat flux can be improved by 5% with 1s-1 angular frequency input. More importantly, inducing swirls at the tower outlet is still the optimal choice for increasing the air draft speed through the tower. With 2s-1 angular frequency input, the thermal performance of the tower can be enhanced by 11~17% in accordance with the crosswind speed.

The transonic centrifugal turbine which shows high single-stage enthalpy drop, small space occupation, simple structure and high aerodynamic efficiency is suitable for small-to-medium scale industrial steam turbine and waste energy utilization. In this paper, the superheated steam was used as the working substance by adopting aerodynamic design method of conventional turbine. Based on the inlet and outlet thermodynamic parameters of a small-sized axial flow steam turbine, the study of one-dimensional aerodynamic design, three-dimensional numerical simulation and optimization, and performance analysis under off-design condition were carried out. Simulation results based on k-e turbulence model are basically in agree with the one-dimensional aerodynamic design value. There shows reasonable flow field and smooth streamlines in the cascade passage with high efficiency and relatively good aerodynamic performance. In this way, the reliability and validity of one-dimensional aerodynamic design procedure of centrifugal turbine is demonstrated. Finally, the centrifugal turbine is analyzed with various rotational speeds and backpressures under different off-design conditions. The simulation results demonstrate that the transonic centrifugal turbine has a good off-design performance under the given off-design conditions.

A new draft equation involving swirling motions for natural draft dry cooling towers (NDDCTs) is derived and solved analytically. A 2-D axisymmetric model for a short NDDCT is built and computational fluid dynamics (CFD) simulations are carried out to verify the theoretical predictions. Results show that the optimized location for swirl input is at the tower outlet to avoid the swirl decay. It is noted that the swirl influence on the air flow draft velocity gradually becomes significant especially when the dimensionless input swirl ratio exceeds 2. The theoretical predictions generally agree with the numerical results, but deviate when: (1) vortices adjacent to the wall occur in the presence of excessively strong swirl, in the case with swirl created by a thin source zone; (2) cold air inflow penetrates due to the significant heat exchanger resistance coefficient; (3) vortex breakdown appears, in the case with swirl filling the whole tower. All the aforementioned unfavourable phenomena are local effects and thus cannot be predicted by the draft equation unless proper local resistance terms are added.

Against the backdrop of energy conservation and emission reduction, the development of power generation technology has always been focusing on higher efficiency with lower cost, where using renewable energy source or waste heat is one of the solutions. The supercritical CO2 Brayton cycle (SCBC) not only predicts remarkable advantages of high efficiency and compact equipment sizes in the moderate temperature range (450¿750 °C), but also provides the disadvantages of material problem due to high temperature and pressure. The SCBC can be applied to solar energy, nuclear power, high-temperature fuel cells and waste heat sources. This paper makes a description of the SCBC as well as the properties of its working fluids supercritical CO2. In addition, the paper also summarizes different structural forms of SCBC, applications of SCBC to different heat sources, thermodynamics of SCBC, multi-objective optimization of thermodynamics and economics of SCBC, complete test equipment of SCBC, and main components design of SCBC. Future researches should focus on raising the efficiency of turbomachinery, designing compact heat exchangers, building up large-scale experimental facility, optimizing configurations of SCBC, and improving control strategies, etc. In short, SCBC is promising, but it still requires more researches on commercialization.

In this paper, a new type of blade model driven by single input for vertical axis wind turbine was developed, and it could achieve synchronous active deformation for both of blade leading edge and trailing edge. Firstly, by taking the concept of ribs and by taking NACA0012 airfoil as an example, the mechanical structure and skin with adhesion mechanism of pre-tightening force was adopted based on the continuous deflection and deformation mode of the blade leading and trailing edges with constant thickness. In this way, the adaptive blade could achieve reciprocating smooth deformation with different cambers. Secondly, the experimental platform for measurement of wind tunnel force and flow visualization was built up, where the smoke wire instrument, seven-hole probe, two-component balance were applied for measuring of quasi steady force and flow visualization under different deformation quantities. Finally, the aerodynamic performance of adaptive blade under different deformation factors was revealed. It is found that within an appropriate range of deformation factor, the blade aerodynamic performance can be improved by deforming. When exceeding the critical camber, the friction resistance becomes a dominant factor effecting blade aerodynamic performance. In all, the experimental results in this paper could provide reference for subsequent unsteady experiments.

The aerodynamic performance of the blade determines the power and load characteristics of a wind turbine. In this paper, numerical research of the active deformation of an airfoil with equal thickness camber line was carried out, which shows the great potential of this active flow control method to improve the flow field. The NACA0012 is taken as the reference airfoil, and the inflow wind speed is 9 m/s, the chord length of the airfoil is 0.4 m, and the Reynolds number is 2.5 × 105. The influence factors, such as deformation amplitude and deformation frequency on the aerodynamic performance, were studied at different attack angles before and after stall. Studies have shown that: Firstly, at different angles of attack, different deformation amplitudes and frequencies have great influence on the aerodynamic performance of the active deformed airfoil. The active deformation can improve the aerodynamic performance of the airfoil in different degrees in deep stall and light stall regions. Secondly, a suitable deformation amplitude and deformation frequency can improve the aerodynamic performance of airfoil stably and effectively in light stall, which occurs when the deformation amplitude equals to 0.02c and the deformation frequency is lower than 2 Hz, and the maximum lift-drag ratio can be increased by about 25%. Before stall, when the deformation frequency is 2 Hz and amplitude is 0.10c, the airfoil will have a negative drag coefficient in the process of deformation, and the airfoil will produce a thrust which is similar to the energy capture of the flapping foil. This is an unexpected discovery in our research.

Due to the flow separation on the blade of the NREL Phase VI wind turbine, a new flow control technique involving installation of an off-surface vibrating small structure is proposed. By considering the actual flow condition, fluid-solid coupling is applied in which two kinds of microcylinder vibration modes are set up, and the aerodynamic performance is numerically studied. The influence of the vibration modes, amplitude, and frequency of the off-surface vibrating small structure on the aerodynamic performance is explored. For various stall conditions, the flow separation can be well suppressed by utilizing a suitable vibrating microcylinder rather than a static microcylinder. In addition, the vibrating microcylinder shows a noticeable suppression effect on large flow separation. Both the vibration direction and vibration amplitude play leading roles in the improvement of the aerodynamic performance, and a microcylinder with a high vibration frequency can more quickly suppress surface flow separation to achieve an optimum aerodynamic performance than a microcylinder with a low vibration frequency. By setting microcylinders with suitable vibration rules close to the blade surface, the wind energy coefficient can be obviously increased compared with those obtained when adding a static microcylinder or without microcylinder addition.

For NREL Phase VI horizontal axis wind turbine, a flow control method to suppress the flow separation by setting micro-cylinder in front of the blade leading edge is proposed, and the corresponding numerical simulation analysis for the aerodynamic performance of wind turbine is conducted. Firstly, the results predicted by simulation are confirmed experimentally. Under the same operating condition, the simulation and experimental results of low-speed shaft torque are compared, along with results from other studies. It can be found that the simulation results can accurately reflect the basic physical characteristics of flow field for NREL Phase VI wind turbine. Secondly, the influence of different diameters and positions of micro-cylinders on aerodynamic performance of wind turbine is discussed. Numerical results suggest that under different stall conditions, setting appropriate micro-cylinders in front of the blade leading edge can effectively suppress flow separation on wind turbine blades without increasing the load of wind turbine. Moreover, under different wind speeds, micro-cylinders with different diameters and positions have various impacts on aerodynamic performance of wind turbine. Through numerical calculation, the blade torque can maximally have an increase of 27.3% by setting a micro-cylinder with proper diameter and position in front of the blade leading edge.

Centrifugal turbine presents good aerodynamic and geometric compatibility. The straight blade can be directly used without significant effect on three dimensional flow field, and therefore the optimum values of the speed ratio and reaction degree can keep constant along the spanwise direction with higher turbine efficiency and simpler manufacturing. Furthermore, the closed impeller which is made by fixing the blade tip using cover band shows larger impeller strength and is suitable for high-speed rotation. In recent years, the centrifugal turbine with many potential advantages is gradually becoming a research hotspot in the field of turbine. In this paper, three kinds of volutes with different cross section shapes were designed for a single-stage centrifugal turbine unit. Based on the CFD simulation in the whole flow passage, the analysis of three-dimensional steady flow for the designed centrifugal turbine was carried out under both of design and off-design conditions, and the following results were obtained: the aerodynamic performance of centrifugal turbines with three kinds of volutes are almost the same under both of design and off-design conditions. Besides, the pear shaped volute shows slightly higher total efficiency, and its overall efficiency, stage internal efficiency and power are 87.36%, 85.79% and 484.88 kW, respectively.

This paper presents a review of numerical models for simulation of gas-solid flow in bypass pneumatic conveying. The kinetic theory, conventional frictional-kinetic model and a new modified frictional-kinetic model are described in some detail. The experimental results for pressure drops based on a number of test cases are presented and compared with numerical results obtained with different numerical models. The convergences of the modified frictional-kinetic model with different values of constants are also illustrated. Moreover, the fluidisation charts of different materials with flow mode boundaries are presented to provide guidance on what frictional approach to use for Computational Fluid Dynamics (CFD) analysis of gas-solid flow in a bypass pneumatic conveying system. Furthermore, a flow chart for the CFD simulation methodology of bypass pneumatic conveying is demonstrated. These outcomes and the associated design guidelines could assist in choosing the most appropriate models for simulation of pneumatic conveying.

Utilizing the UCFD (Unified Computational Fluid Dynamics) software, this paper describes simulation of the extraction of marine tidal energy using a flapping hydrofoil. Firstly, the validity of the numerical simulation was confirmed, where the time signal of heave force coefficient agreed well with the experimental result. Secondly, a parameter optimization study was conducted under different influence factors, results such as heaving force and work done by the heaving and pitching motions were analyzed and compared. When the quarter-period effective angle of attack is 34.4°, the heaving amplitude is 1.0c or the Strouhal number is 0.36, the power efficiency of the flapping foil was found maximized. Finally, by combining the vortex variation and pressure coefficient distribution on the hydrofoil surface at different moments, it was found that if there is a relatively large leading edge vortex at the bottom surface of the foil at 0.25¿T, and also if the difference between the pressure coefficients for top and bottom surfaces is relative large, then a high power efficiency could be achieved. This result could be used as a necessary, but not precisely sufficient¿condition for evaluating the power extraction, since the pitching amplitude should also be considered for analysis.

By utilizing the UCFD software, this paper numerically investigated the energy extraction of flapping hydrofoil in current. Firstly, the simulation result was verified by comparing with related experimental results. Secondly, with different series of hydrofoil shapes, simulation was conducted for energy extraction of flapping foil moving harmonically in current. Several results were found in this research: for NACA 4 series hydrofoils, the energy extraction efficiency basically increased first and then decreased with the increase of thickness of hydrofoil; for NACA 6, A, S and FX series hydrofoils, the energy extraction efficiency increased with the increase of thickness of hydrofoil; for hydrofoils with small difference of camber, if the hydrofoils had similar thickness and similar mode of formation and dissipation of vortex, the energy extraction efficiencies were close; for hydrofoils with the same thickness, the energy extraction efficiency decreased when the position of the maximum thickness of the hydrofoil was closer to the trailing edge; for thin hydrofoils, the symmetric hydrofoils showed higher energy extraction efficiencies than asymmetric hydrofoils; with generation and shedding of leading edge vortex at proper position, the energy extraction efficiency could be increased accordingly

Any technique or method that can improve the efficiency in exploiting renewable wind or marine current energy has got a great significance today. It has been reported that adding a winglet at the tip of the rotor blades on a horizontal axis wind turbine can increase its power performance. The purpose of this paper is to adopt a numerical method to investigate the effects of different winglet configurations on turbine performance, especially focusing on the direction for the winglet tip to point towards (the suction side, pressure side or both sides of the main blade). The results show that the new design of an integrated fusion winglet proposed in this paper can generally improve the main blade's power producing ability, which is further enhanced with the increase of turbine's tip speed ratio with a maximum power augmentation of about 3.96%. No matter which direction the winglet tip faces, the installation angle of the winglet should match well with the real angle of incoming flow. As a whole, the turbine with winglet of two tips facing to both sides of the main blade can produce much more power than the one of winglet configuration whose tip faces only one side for different blade hub pitch angles and vast majority of tip speed ratios. The working principle behind the winglet in improving turbine performance may be that it can block the downwash fluid easily flowing around the tip section of the main blade from the pressure side to suction side, and hence diffuse and spread out the tip vortex. As a result, it finally decreases the energy loss. Besides, the relative projected rotor area in incoming flow direction will also be reduced due to the addition of the winglet, which is also helpful to turbine's power coefficient.

The geometric factors which influence airfoil aerodynamic performance are attributed to variations in local first- and second-order curvature derivatives. Based on a self-developed computational fluid dynamics (CFD) program called UCFD, the influence of local profile variations on airfoil aerodynamic performance in different pressure areas is investigated. The results show that variations in first- and second-order derivatives of the airfoil profiles can cause fluctuations in airfoil aerodynamic performance. The greater the variation in local first- and second-order derivatives, the greater the fluctuation amplitude of the airfoil aerodynamic coefficients. Moreover, at the area near the leading edge and the shock-wave position, the surface pressure is more sensitive to changes in first- and second-order derivatives. These results provide a reference for airfoil aerodynamic shape design.

Bypass pneumatic conveying is an alternative way to convey material which does not have dense phase transport capability. The computational fluid dynamics based commercial software Fluent 6.3 is used to investigate the pressure drop as well as the gas¿solid flow behaviour in a bypass pneumatic conveying system. The conveyed material was sand with a mean particle size of 378 µm and the solid loading ratio was in the range of 10¿123. The conventional frictional-kinetic model combining frictional and kinetic stresses simultaneously was applied for pressure drop prediction. The simulation results were then compared with experimental results from bypass pneumatic conveying tests. Selected image results from the computational fluid dynamics simulations were utilised and compared with images captured from high speed camera. In addition, a test case with low air mass flow rate and high solid loading ratio 82.49 was chosen as an example to show detailed gas¿solid flow behaviour in the simulation of highly dense flows. It was found that conventional frictional-kinetic model with modified packing limit and friction packing limit has greatly improved the pressure drop prediction result compared with kinetic theory without friction. The detailed analysis for the selected test case showed how the full bore dune formation and deformation of sand and bypass flutes interact. High amplitude fluctuations and variation in pressure and gas velocity were observed. The gas velocity vectors indicate a high degree of air penetration from the flute into the bypass pipe. This behaviour provides an aeration mechanism which is what makes the bypass system work and allows non-dense phase material to be conveyed in a dense mode of flow.

A new frictional-kinetic model is proposed and modified for pressure drop prediction of alumina in a bypass pneumatic conveying system. This new model is based on the conventional Johnson-Jackson frictional-kinetic model. The critical value of solids volume fraction and maximum packing limit are modified based on the fluidized bulk density and tapped bulk density, respectively. In addition, an offset solid volume fraction is introduced into the frictional pressure model as well as into the radial distribution functions which represents the correction factors to modify the probability of collisions between particles when solid phase becomes excessively dense. For the application of the model, computational fluid dynamics (CFD) simulations were conducted by using kinetic theory, conventional frictional-kinetic model and modified frictional-kinetic model. The simulation results were then compared with the experimental results. It was found that the modified frictional-kinetic model showed the largest improvement on pressure drop prediction results compared with results obtained from applying the kinetic theory and the conventional frictional-kinetic model, especially for denser flows with low air mass flow rates and high solid loading ratios (SLR). In addition, the solids volume investigation of CFD simulations shows a strong comparison to the actual flow conditions in the pipe, as transient slug type flow of alumina is observed.

In this paper, a novel Darrieus vertical axis wind turbine was designed whose blade can be deformed automatically into a desired geometry and thus achieve a better aerodynamic performance. A series of numerical simulations were conducted by utilizing the United Computational Fluid Dynamics code. Firstly, analysis and comparison of the performance of undeformed and deformed blades for the rotors having different blades were conducted. Then, the power characteristics of each simulated turbine were summarized and a universal tendency was found. Secondly, investigation on the effect of blade number and solidity on the power performance of Darrieus vertical axis wind turbine with deformable and undeformable blades was carried out. The results indicated that compared to conventional turbines with same solidity, the maximum percentage increase in power coefficient that the low solidity turbine with three deformable blades can achieve is about 14.56%. When solidity is high and also turbine operates at low tip speed ratio of less than the optimum value, the maximum power coefficient increase for the turbines with two and four deformable blades are 7.51% and 8.07%, respectively. However, beyond the optimal tip speed ratio, the power improvement of the turbine using the deformable blades seems not significant and even slightly worse than the conventional turbines. The last section studied the transient behavior of vortex and turbulent flow structures around the deformable rotor blade to explore the physical mechanism of improving aerodynamic performance. The adaptive blades could obviously suppress the separation of flow from the blade surfaces.

The hump characteristic often appears in the performance curve of an axial flow fan. The main purpose of this paper is to study the impact on performance when considering the casing slot arrangement direction with respect to the rotation axis with a numerical method. The results shows that all the slot design schemes can improve the performance to a certain extent and broaden the stable operation range of the axial flow fan. The casing slot can move the best efficiency point to the direction of small flow rate. While during the large flow area, the total pressure rise and efficiency will slightly decrease. The slot scheme of inverse blade 45° to the axial direction obtains the optimal comprehensive performance within the full working conditions. The performance improvement for the leading arrangement of circumferential slots is almost the same with the whole layout. The main cause of performance improvement for an axial flow fan with proper casing treatment, may be that the high pressure fluid can flow smoothly around the blade tip from the pressure side to the suction side, and the low energy vortex will be swept away timely and moved downstream, which will effectively restrain the flow separation on the blade surfaces and flow blockage in the blade tunnels, and also reduce the vortex generation and the secondary flow loss.

As a new mode of energy extraction, flapping foils show broad application prospects. How to improve the energy extraction efficiency (¿) of wind or hydro energy with flapping foils has become a focused issue for scientists in this field. This paper numerically investigated the energy extraction of flapping hydrofoil with different NACA 4 and NACA 6 series foil shapes. Firstly, compared with experimental results, the simulation results were validated. Secondly, by adopting different series of foil shapes, simulation was conducted for energy extraction of flapping foils which were moving harmonically in current: ¿ symmetric foils with different maximum thicknesses; ¿ symmetric foils with different maximum thickness positions; ¿non-symmetric foils with same maximum thickness, maximum thickness position and camber, but different maximum camber positions; ¿ non-symmetric foils with same maximum thickness, maximum thickness position and camber position, but different maximum cambers. It is found that for symmetric foils with different maximum thicknesses, ¿ basically increases first and then decreases with the increase of maximum thickness; for symmetric foils with different maximum thickness positions, ¿ first increases and then decreases when maximum thickness position moves from the leading edge to the trailing edge; for non-symmetric foils with same thickness, ¿ shows lower value with larger camber; compared with maximum camber position, the maximum thickness shows larger influence on ¿.

In this work, in-house computational fluid dynamics (CFD) code was utilized to simulate a cross-flow vertical-axis marine current turbine (straight-bladed Darrieus type). Particular emphasis was placed on the influence of interaction between vortices and blades on hydrodynamic performance. A physical transient-rotor-stator model with a sliding mesh technique was used to capture changes in flow field at a particular time step. The Spalart-Allmaras turbulence model was adopted for the turbulence. For a Darrieus-type marine current turbine, hydrodynamic characteristics such as power coefficient and flow behavior were then numerically investigated. The results suggest that vortices shed from previous blade passages and the close encounter of a rotor blade with these vortices can cause a variation in performance for this type of turbine during operation at different tip speed ratios.

Oscillating foil machines represent a type of flow energy harvesters which perform pitching and plunging motions simultaneously to harness the energy from incoming stream. In this paper, a new adaptive deformation oscillating wing was proposed and the theoretical performance of such a concept was studied here through unsteady two-dimensional simulations using an in-house developed computational fluid dynamics code. During operation, the proposed oscillating foil whose initial shape is symmetric can be deformed into a cambered foil, which aims to produce large lift force. Our numerical results suggest that the power efficiency of the proposed oscillating foil can be about 16.1% higher than the conventional oscillating foil without deformation. In addition, the effects of the maximum bending displacement and effective angle of attack on the efficiency of proposed oscillating foil were also discussed in this work.

This paper numerically investigated the possibility of creating supercavitation through an artificially induced increase in the surface temperature of the underwater vehicle. Firstly, in order to consider the influence of thermomechanical effect on the cavitation process, the Zwart-Gerber-Belamri (ZGB) cavitation model was modified. By comparing with the experimental results, the accuracy of the modified model was validated. Secondly, the modified cavitation model was used to simulate the cavitating flows over a hemisphere cylinder body whose surface was heated to different temperatures. With the aid of CFD software ANSYS CFX, the variation of the bubble volume fraction and skin friction drag of the hemisphere cylinder at different cavitation numbers and heating temperatures were obtained and analyzed. The results show that the generation and development of cavity can be promoted by using the heating method. In this way, the friction resistance on underwater vehicle surfaces can be reduced effectively. There exists an optimal heating temperature to make the cavitation bubbles fully developed and cover the whole outside surface of underwater vehicle. By this means, the friction resistance on underwater vehicle surfaces can be reduced effectively, and the speed of vehicle can increase accordingly.

Vertical axis wind turbine has attracted much attention for the advantages such as the simple structure, without upwind device, simple motion, easy manfacture, low cost and so on. Vertical axis wind turbine can be divided into Darrieus and Savonius. In general, the Darrieus VAWT have higher wind power efficiency compared to the Savonius VAWT. Otherwise, the Darrieus VAWT are not always self-starting. This paper studies the performance of the spiral VAWT using CFD. Numerical results suggest that the spiral VAWTs have good aerodynamic and starting performance.

A recently developed in-house computational fluid dynamics (CFD) code is used to simulate an H-Darrieus wind turbine. Aerodynamic performance of the simulated Darrieus turbine having different number of blades and turbine solidity is analyzed and compared for different tip speed ratios. As expected, the power coefficient of the simulated Darrieus turbine increases with the increase of tip speed ratio until a maximum is reached. However, the power coefficient then decreases with further increases in the tip speed ratio. The calculated power curve is in good agreement with experimental results. The results obtained suggest that this developed CFD code can accurately predict the aerodynamic characteristics of an H-Darrieus turbine. In addition, it is found that the solidity has considerable influence on the power coefficient of the simulated turbine in the present work. The smaller the solidity, the higher will be the optimal tip speed ratio and the wider will be the range of tip speed ratios at which the H-Darrieus turbine remains high power coefficient. If solidity is very low, the performance of a 2-bladed Darrieus turbine is obviously better than that of turbines with 3 and 4 blades. For moderate to high solidity, the power coefficients of the 2-bladed Darrieus wind turbine are similar to those of the 3-bladed turbine and are higher than those of the 4-bladed turbine. Moreover, the power coefficient increases with increasing solidity at low tip speed ratios. When the tip speed ratio is close to the optimum value, the power coefficient initially increases and then decreases with the increase of solidity. At high tip speed ratio, the power coefficient decreases with increasing solidity. An in-depth investigation is also conducted on the findings observed in this study and presented in Part 2 of this work, in which the mechanism of the effect of solidity on power coefficient has been explored based on the vortex structure of the flow field with the aid of this self-developed CFD code. © 2014 AIP Publishing LLC.

Bypass pneumatic conveying systems provide the capacity of transporting some materials that are not naturally suited to dense phase flow in a low velocity, dense phase flow regime. Bypass pneumatic conveying systems also provide a passive capability to reduce minimum particulate transport velocities. Therefore, particle degradation and pipe line wear can be much reduced. In this paper, the operation of internal bypass system was investigated by both experiments and modelling. An entire bypass system was numerically modelled based on the mass conservation. An integrated version of the Ideal Gas Equation was applied to evaluate pressures at the central point of each node for air flow in the bypass pipe and the main pipe. The bypass pneumatic experimental system was built with a main pipe of 79mm in diameter and an internal bypass pipe with orifice plate flute arrangement. Fly ash and alumina were used in the tests. High speed video camera visualization and differential pressure transmitters were employed to investigate the operation of dense phase bypass pneumatic transport systems and the mechanism of material blockage inhibition provided by this system. The bypass system was found to consume more energy than conventional system when using the same air mass flow rate due to the increase of friction. The conveying velocity of alumina in bypass system was much lower than that of conventional pipelines, which resulted in much reduced specific energy consumption. In this system, particulate material blockages were inhibited in bypass systems due to the air penetration into the particulate volume, as was reflected in differential pressure transmitter measurement data and flow visualization.
