Career Summary
Biography
Dr Orozovic completed a Bachelor degree in Mechanical Engineering as an undergraduate industry scholar with TUNRA Bulk Solids and a PhD at the Centre for Bulk Solids and Particulate Technologies (CBSPT). His Honours and PhD projects were both in multiphase flow (pneumatic conveying), which remains the main research area for Dr Orozovic. Still an early career researcher Dr Orozovic was the primary supervisor of a PhD project in pneumatic conveying, which was completed by publication, and has successfully attracted competitive funding in pneumatic conveying from the ARC and industry.
Currently, Dr Orozovic is a research associate at CBSPT and outside of pneumatic conveying is also active in the areas of dewatering and transfer chutes. Broadly speaking, his interests are in mathematical modelling of bulk solid materials, systems and processes and Dr Orozovic has strong ties with the applied mathematics group at the University of Newcastle. International collaboration has also been established with researchers from the Pacific, Asia, Europe and North America – most notably the longstanding collaboration with leading expert in pneumatic conveying Emeritus Professor George Klinzing from the University of Pittsburgh.

[more] The throughput of a belt conveyor system is the primary design parameter when considering a new installation, determined by the cross-section of the material on the belt, coupled with the belt speed. Optimizing this area not only improves efficiency, but also minimizes capital costs through the optimal selection of equipment. Whilst speed-related optimization has seen considerable attention, the cross-sectional area has largely been neglected due to existing design constraints of the system. Conventional belt conveyors typically utilize a 3-idler troughing configuration, which forms a trapezoidal cross-section with a parabolic surcharge. The rigidity of this support directly limits the geometry of the cross-section that may be considered. A new conveyor system developed at the University of Newcastle supports the conveyor belt by a rail-based carriage, with no relative movement between the belt and carriage. This configuration allows the cross-section of the belt to be freely optimized in order to maximize the material throughput for a given belt width, or alternatively to minimize the belt width for a given throughput. This article utilizes the calculus of variations to optimize the form of this cross section, and demonstrates that an increase in throughput of up to 30% is possible, compared to troughed installations.

[more] The effect of oscillation on the water distribution in unsaturated coal and iron ores plays a significant role in the material processing but has not been analysed quantitatively. This paper developed a model based on the Richards equation to describe the transient residual water distribution in the unsaturated coal and iron ores, and predicted the separated water with time. In this model, the effect of oscillation was quantised as a dynamic potential of the unsaturated water. The model was experimentally verified and applied to characterise the separated and residual water. The effects of initial water content, hydraulic conductivity, dynamic potential and bottom boundary were quantitatively analysed. The results showed that the dynamic potential affects the transient and steady water distribution for the overall height of the coal and iron ores. These findings can be applied to the minimisation of water distribution in wet coal or iron ores and optimisation of their processing.

This paper considers a series of experiments using fuzzy cottonseeds, which greatly differ in particle and bulk properties from fine powders, to investigate plug formation. In this study, several possible dense phase behaviours were observed, which were consistent in vertical and horizontal orientations and mostly influenced by the batch size of feeding into the rig due to its influence on particle arrangement. Particle arrangement at the plug base or rear was found to be critical for achieving stable plugs, with a requirement of the rear or base batch having the length of more or equal to pipe diameter. This work sheds light on the general features and mechanisms governing horizontal and vertical plug formation.

Initial slug length, inlet velocity and initial stationary layer fractions were systematically varied for a total of 72 simulations. Previously made observation that slugs tend towards a steady state was confirmed via a theoretical derivation. The derivation shows that slugs move towards their steady state lengths exponentially. This allowed for a calculation of a characteristic time scale which is a measure of how quickly a slug tends towards the steady state. The theoretical estimate which is a function of slug porosity, steady length, velocity and stationary layer fraction has good agreement with simulated results. A link between steady slug length and solids loading ratio was also shown.

The accuracy of the IMU was assessed and compared to particle image velocimetry (PIV) and once good agreement was confirmed it was used to investigate various aspects of slug flow. Relative movement between core particles and slugs tails and heads was assessed using relative pressures and quantified times spent in a slug. It was found that the propagation of particles backwards through a slug is relatively constant. Pressure-velocity relationship was observed that was theorised to be related to variations in stationary layer ahead of the slugs. Observations of further nuanced features of slug motion are also included to demonstrate the capabilities of IMUs in capturing the many dynamic aspects of the flow.

The first method consists in applying a permeability model in combination with measurements of pressure loss and fluid velocity along the slugs. A review of existing models describing the resistance of porous structures to fluid flow revealed that the semi-empirical model of Ergun is particularly suitable to investigate the porosity profile along moving slugs. The second method consists in a direct determination method involving a slug-catcher able to catch a moving slug in a fraction of a second and simultaneously separate it into three horizontal layers. Those two methods were applied to analyse the porosity of naturally occurring slugs during pneumatic transport of polypropylene pellets. It was found that in contrast to common belief, slugs are slightly fluidised structures that do not display any porosity gradient over the pipe cross-section height. The slug porosity appeared independent of the gas conveying velocity, all slugs displaying an average porosity around 0.41, which is slightly higher than the bulk porosity of 0.38. Most of the slugs displayed a rear that is denser than the front. However, some slugs had a front that is denser than the rear while other slugs displayed a relatively constant porosity over the entire length. Those unique results refuting the commonly used hypothesis that slugs are compact structures give a new incentive to the area of slug flow pneumatic conveying. While bulk solids mechanics can no longer be applied to explain the stresses induced by moving slugs, the validity of other theories that imply that slugs are fluidised structures should be investigated. © 2013 Elsevier B.V.

Slug characteristics including the profile of pressure, pressure gradient, particle velocity, porosity, radial and wall shear stresses, aspect and behaviour were combined to obtain a complete picture of moving slugs. The objective was to gain unique knowledge on the physical mechanisms involved in slug formation, transport, and decay and the occurrence of pipe blockage. Slugs in both stable and unstable states were analysed. A strong correlation between particle velocity and wall stresses was found, which suggests that the stresses responsible for the high pressure loss characterising slug flow may result mostly from the transfer of particle impulses to the pipe wall. Most slugs were found to be denser at the rear where particle velocity was the highest, thus leading to slug shortening over time. This phenomenon was successfully modelled using both Newton's 2nd law and the ideal gas law and prediction of particle velocity showed good agreement with experimental values. In contrast, other slugs were found to extend due to the particles at the front moving faster than the particles at the rear. Pipe blockage was found to result from insufficient permeation of the slug by the conveying gas, indicating that sufficient material permeability is a condition for slug flow to occur. © 2014 Elsevier B.V.

The gas-liquid analogy model of Konrad has been shown to accurately predict the layer fraction for a range of cases but the model breaks down near blockage conditions and does not consider material properties. A new model based on the rate of change of the layer fraction with respect to slug velocity was developed that accounts for material properties and is applicable at blockage conditions. Results from tests on polypropylene pellets were compared to the new model and the model of Konrad with both models satisfactorily predicting the layer fraction in the range of slug velocities that were observed for the material. At the higher extremity of slug velocity the new model predicted an earlier onset of a change in flow types than the model of Konrad which was supported by experimental observations but not enough data was obtained on the test material to compare predictions near blockage conditions. A material dependent constant in the new model was found for polypropylene pellets with further investigations needed to explore this constant as a predictive or classifying tool for materials and their ability to slug.
