Â© 2016 Cambridge University Press.Selfpreservation (SP) solutions on the axis of a turbulent round jet are derived for the transport equation of the secondorder structure function of the turbulent kinetic energy , which may be interpreted as a scalebyscale (s.b.s.) energy budget. The analysis shows that the mean turbulent energy dissipation rate, , evolves like ( is the streamwise direction). It is important to stress that this derivation does not use the constancy of the nondimensional dissipation rate parameter ( and are the integral length scale and root mean square of the longitudinal velocity fluctuation respectively). We show, in fact, that the constancy of is simply a consequence of complete SP (i.e. SP at all scales of motion). The significance of the analysis relates to the fact that the SP requirements for the mean velocity and mean turbulent kinetic energy (i.e. and respectively) are derived without invoking the transport equations for and . Experimental hotwire data along the axis of a turbulent round jet show that, after a transient downstream distance which increases with Reynolds number, the turbulence statistics comply with complete SP. For example, the measured agrees well with the SP prediction, i.e. , while the Taylor microscale Reynolds number remains constant. The analytical expression for the prefactor for (where is a virtual origin), first developed by Thiesset et al. (J. Fluid Mech., vol. 748, 2014, R2) and rederived here solely from the SP analysis of the s.b.s. energy budget, is validated and provides a relatively simple and accurate method for estimating along the axis of a turbulent round jet.

Â© 2015, SpringerVerlag Berlin Heidelberg.In this paper, the velocitybased POD and the vorticitybased POD have been systematically compared in three characteristic regions of the flow downstream of a twodimensional circular cylinder, namely the near, intermediate and far wakes. The twopoint space correlation function is used to determine which of the two methods is better suited for extracting the largescale flow structures based on the repartition of energy among the different POD modes. It is found that the POD, based on the lateral velocity fluctuation v, leads to the most optimum extraction in all three flow regions, while the vorticitybased POD is only effective in the near and intermediate wakes. Based on twopoint space correlation functions, a scenario is proposed for the application of POD to the present twodimensional wake.

Hotwire velocity measurements are carried out in a turbulent boundary layer over a rough wall consisting of transverse circular rods, with a ratio of 8 between the spacing (w) of two consecutive rods and the rod height (k). The pressure distribution around the roughness element is used to accurately measure the mean friction velocity (Ut) and the error in the origin. It is found that Ut remained practically constant in the streamwise direction suggesting that the boundary layer over this surface is evolving in a selfsimilar manner. This is further corroborated by the similarity observed at all scales of motion, in the region 0.2=y/d=0.6, as reflected in the constancy of Reynolds number (RÂ¿) based on Taylor's microscale and the collapse of Kolmogorov normalized velocity spectra at all wavenumbers.A scalebyscale budget for the secondorder structure function <(du)2> (du=u(x+r)u(x), where u is the fluctuating streamwise velocity component and r is the longitudinal separation) is carried out to investigate the energy distribution amongst different scales in the boundary layer. It is found that while the small scales are controlled by the viscosity, intermediate scales over which the transfer of energy (or <(du)3>) is important are affected by mechanisms induced by the largescale inhomogeneities in the flow, such as production, advection and turbulent diffusion. For example, there are nonnegligible contributions from the largescale inhomogeneity to the budget at scales of the order of Â¿, the Taylor microscale, in the region of the boundary layer extending from y/d=0.2 to 0.6 (d is the boundary layer thickness).

Â© 2015 Cambridge University Press.The transport equation for the isotropic turbulent energy dissipation rate along the centreline in the farwake of a circular cylinder is derived by applying the limit at small separations to the twopoint energy budget equation. It is found that the imbalance between the production and the destruction of eiso, respectively due to vortex stretching and viscosity, is governed by both the streamwise advection and the lateral turbulent diffusion (the former contributes more to the budget than the latter). This imbalance differs intrinsically from that in other flows, e.g. grid turbulence and the flow along the centreline of a fully developed channel, where either the streamwise advection or the lateral turbulent diffusion of eiso governs the imbalance. More importantly, the different types of imbalance represent different constraints on the relation between the skewness of the longitudinal velocity derivative and the destruction coefficient of enstrophy G. This results in a nonuniversal approach of towards a constant value as the Taylor microscale Reynolds number RÂ¿ increases. For the present flow, the magnitude of S decreases initially before increasing (RÂ¿ > 40) towards this constant value. The constancy of S at large RÂ¿ violates the modified similarity hypothesis introduced by Kolmogorov (J. Fluid Mech., vol. 13, 1962, pp. 8285) but is consistent with the original similarity hypotheses (Kolmogorov, Dokl. Akad. Nauk SSSR, vol. 30, 1941b, pp. 299303 (see also 1991 Proc. R. Soc. Lond. A, vol. 434, pp. 913)) , and, more importantly, with the almost completely selfpreserving nature of the plane farwake.

Â© 2015 Cambridge University Press.Selfpreservation (SP) analyses are applied to the mean momentum and the scalebyscale energy budget equations in the far wake of a circular cylinder. The scalebyscale SP analysis, which is a twopoint analysis, complements the SP analysis of the mean momentum equation. Powerlaw variations are derived for different length scales (e.g.the Taylor microscale and the Kolmogorov length scale) and velocity scales (e.g.the root mean square and the Kolmogorov velocity scale). Further, the SP solutions for the scalebyscale energy budget equation are exploited to develop an exact relation to estimate the mean turbulent kinetic energy dissipation rate on the wake axis. These SP solutions and the new relation are well supported by hotwire data in the far wake at a Reynolds number of 2000 based on the free stream velocity and the cylinder diameter. On the farwake axis, both the energy spectra and the structure functions exhibit an almost perfect collapse over all wavenumbers and separations, irrespective of the set of scaling variables used for normalisation. This is consistent with a complete selfpreservation (i.e.SP is satisfied at all scales of motion) in the far wake.

Â© Cambridge University Press 2015.A general framework of selfpreservation (SP) is established, based on the transport equation of the secondorder longitudinal velocity structure function in decaying homogeneous isotropic turbulence (HIT). The analysis introduces the skewness of the longitudinal velocity increment, S(r, t) (r and t are space increment and time), as an SP controlling parameter. The present SP framework allows a critical appraisal of the specific assumptions that have been made in previous SP analyses. It is shown that SP is achieved when S(r, t) varies in a selfsimilar manner, i.e. S=c(t)f(r/l) where l is a scaling length, and c(t) and f(r/l) are dimensionless functions of time and (r/l), respectively. When c(t) is constant, l can be identified with the Kolmogorov length scale Â¿, even when the Reynolds number is relatively small. On the other hand, the Taylor microscale Â¿ is a relevant SP length scale only when certain conditions are met. The decay law for the turbulent kinetic energy (k) ensuing from the present SP is a generalization of the existing laws and can be expressed as k ~ (tt0)^{n}+B, where B is a constant representing the energy of the motions whose scales are excluded from the SP range of scales. When B = 0, SP is achieved at all scales of motion and Â¿ becomes a relevant scaling length together with Â¿. The analysis underlines the relation between the initial conditions and the powerlaw exponent n and also provides a link between them. In particular, an expression relating n to the initial values of the scaling length and velocity is developed. Finally, the present SP analysis is consistent with both experimental grid turbulence data and the eddydamped quasinormal Markovian numerical simulation of decaying HIT by Meldi & Sagaut (J. Turbul., vol. 14, 2013, pp. 2453).

Â© Â© 2015 Cambridge University PressA.Direct numerical simulations (DNS) are carried out to study the passive heat transport in a turbulent channel flow with either square bars or circular rods on one wall. Several values of the pitch to height ratio and two Reynolds numbers are considered. The roughness increases the heat transfer by inducing ejections at the leading edge of the roughness elements. The amounts of heat transfer and mixing depend on the separation between the roughness elements, an increase in heat transfer accompanying an increase in drag. The ratio of nondimensional heat flux to the nondimensional wall shear stress is higher for circular rods than square bars irrespectively of the pitch to height ratio. The turbulent heat flux varies within the cavities and is larger near the roughness elements. Both momentum and thermal eddy diffusivities increase relative to the smooth wall. For square cavities the turbulent Prandtl number is smaller than for a smooth channel near the wall. As increases, the turbulent Prandtl number increases up to a maximum of 2.5 at the crests plane of the square bars . With increasing distance from the wall, the differences with respect to the smooth wall vanish and at three roughness heights above the crests plane, the turbulent Prandtl number is essentially the same for smooth and rough walls.

Â© 2015 Cambridge University Press.The transport equation for the mean turbulent energy dissipation rate along the centreline of a fully developed channel flow is derived by applying the limit at small separations to the twopoint budget equation. Since the ratio of the isotropic energy dissipation rate to the mean turbulent energy dissipation rate is sufficiently close to 1 on the centreline, our main focus is on the isotropic form of the transport equation. It is found that the imbalance between the production of due to vortex stretching and the destruction of caused by the action of viscosity is governed by the diffusion of by the wallnormal velocity fluctuation. This imbalance is intrinsically different from the advectiondriven imbalance in decayingtype flows, such as grid turbulence, jets and wakes. In effect, the different types of imbalance represent different constraints on the relation between the skewness of the longitudinal velocity derivative and the destruction coefficient of enstrophy in different flows, thus resulting in nonuniversal approaches of towards a constant value as the Taylor microscale Reynolds number, , increases. For example, the approach is slower for the measured values of along either the channel or pipe centreline than along the axis in the selfpreserving region of a round jet. The data for collected in different flows strongly suggest that, in each flow, the magnitude of is bounded, the value being slightly larger than 0.5.

Â© 2015 Cambridge University Press.A selfpreservation (SP) analysis is carried out for a zero pressure gradient (ZPG) roughwall turbulent boundary layer with a view to establishing the requirements of complete SP (i.e. SP across the entire layer) and determining if these are achievable. The analysis shows that SP is achievable in certain roughwall boundary layers (irrespectively of the Reynolds number Re), when the mean viscous stress is zero or negligible compared to the form drag across the entire boundary layer. In this case, the velocity scale u* must be constant, the length scale l should vary linearly with the streamwise distance x and the roughness height k must be proportional to l. Although this result is consistent with that of Rotta (Prog. Aeronaut. Sci., vol. 2 (1), 1962, pp. 195), it is derived in a more rigorous manner than the method employed by Rotta. Further, it is noted that complete SP is not possible in a smoothwall ZPG turbulent boundary layer. The SP conditions are tested against published experimental data on both a smooth wall (Kulandaivelu, 2012, PhD thesis, The University of Melbourne) and a rough wall, where the roughness height increases linearly with x (Kameda et al., J. Fluid Sci. Technol., vol. 3 (1), 2008, pp. 3142). Complete SP in a ZPG roughwall turbulent boundary layer seems indeed possible when k Â¿ x.

Â© 2015 Cambridge University Press.The variation of S, the velocity derivative skewness, with the Taylor microscale Reynolds number ReÂ¿ is examined for different turbulent flows by considering the locally isotropic form of the transport equation for the mean energy dissipation rate eÂ¯iso. In each flow, the equation can be expressed in the form S C 2G=ReÂ¿ D C=ReÂ¿, where G is a nondimensional rate of destruction of eÂ¯iso and C is a flowdependent constant. Since 2G=ReÂ¿ is found to be very nearly constant for ReÂ¿ = 70, S should approach a universal constant when ReÂ¿ is sufficiently large, but the way this constant is approached is flow dependent. For example, the approach is slow in grid turbulence and rapid along the axis of a round jet. For all the flows considered, the approach is reasonably well supported by experimental and numerical data. The constancy of S at large ReÂ¿ has obvious ramifications for smallscale turbulence research since it violates the modified similarity hypothesis introduced by Kolmogorov (J. Fluid Mech., vol. 13, 1962, pp. 8285) but is consistent with the original similarity hypothesis (Kolmogorov, Dokl. Akad. Nauk SSSR, vol. 30, 1941, pp. 299303).

For homogeneous isotropic turbulence approximated by grid turbulence, velocity and temperature fluctuations decay under the effects of viscosity and thermal diffusivity of the fluid. In the selfsimilar region of grid flow, there is no mean shear and no turbulence production, and the decay rate is well represented by a power law; this is supported by the present measurements in three different grid flows and by previously published data for passivegrid turbulence obtained over different ranges of streamwise distance and/or Reynolds number. The grid flow is slightly heated so that temperature acts as a passive scalar. From dimensional analysis and empirical powerlaw correlations, relations for basic flow parameters, such as the Kolmogorov, Taylor, and Corrsin microscales, and the Reynolds and PÃ©clet numbers, are established as functions of the normalized streamwise distance downstream of the grid. With these relations, it is possible to determine the flow parameters for a specific passivegrid geometry or, more generally, a specific set of initial conditions.

This article focuses on the effect that two different mesh grids have on the structure of the mixing layer of an axisymmetric jet. Detailed measurements of mean velocity and turbulent velocity fluctuations are made with an X hotwire probe in the range 0.5 = x/d = 10, where x is the longitudinal distance from the nozzle exit plane and d is the nozzle diameter. The grids are introduced at two locationsone location just downstream of the nozzle exit plane and the other location upstream of the nozzle exit plane in order to perturb the nozzle exit boundary layer. One mesh completely covers the nozzle (full mesh or FM) and the other mesh covers the central, highspeed zone (disk mesh or DM). With reference to the undisturbed jet, FM yields a significant reduction in the turbulence intensity and width of the shear layer, whereas DM enhances the turbulence intensity and increases the width of the shear layer. Both grids suppress the formation of the KelvinHelmholtz instability in the mixing layer. Results are presented, mainly at x/d = 5 and 6 in both the spectral domain and physical space. In the latter context, secondand thirdorder structure functions associated with u (the longitudinal velocity fluctuation) and v (the lateral or radial velocity fluctuation) are presented only for the flow perturbed by placing the mesh outside the nozzle. All mesh geometries have a more significant effect on the secondorder structure function of u than on that of v. The thirdorder energy transfer term is affected in such a way that, relative to the undisturbed jet, its peak location is shifted to a smaller scale when FM is used and to a larger scale with DM. This is consistent with our observations that FM reduces the turbulence in the shear layer while DM enhances it. It is suggested that the largescale vortices that are formed at the edge of the grids play a significant role in the transfer of energy. Â© 2013 Taylor & Francis Group, LLC.

We investigate the effect of the hot wire resolution on measurements of the velocity derivative skewness in homogeneous isotropic turbulence. A single wire configuration (with different lengths and temporal sampling resolutions) is considered. Estimates of the attenuation, based on numerical data in box turbulence, are applied to experimental data taken in grid turbulence. It is found that the sampling resolution has a sizeable attenuation effect, while the length of the wire has a relatively minor impact. The corrected experimental values support the conclusion that the skewness is constantwith the Reynolds number, in agreement with Kolmogorov's 41 theory.

Decaying grid turbulence is considered at low Reynolds number (R Â¿~ 50) for different initial conditions. Three different grid geometries are used. Heat is injected via a mandoline at a distance of 1.5 M from the grid. The amount of heating is such that temperature may be treated as a passive scalar. A small contraction (1.36:1) is added at a distance of 11M downstream of the grid. The powerlaw exponents for the scalar variance are compared with those for the turbulent kinetic energy. These exponents depend on the grid geometry. For the isotropic dissipation rate (Chi;) iso, the powerlaw exponent agrees with that inferred from the temperature variance transport equation. Restricting the range of validity of the decay law affects the magnitudes of the origin and decay exponent. Secondorder temperature structure functions collapse when the normalization is based on the local temperature variance and the Corrsin microscale but the asymptotic form of this collapse depends on the initial conditions.

DNSs of turbulent channel flows with one rough wall and one smooth wall are presented to show how the vorticity field depends on the shape and orientation of the roughness elements. The passive scalar is also evaluated. The high correlation coefficients between vorticity and scalar gradients, in the wall layer, emphasize that in all cases flowvisualizations can be used in a laboratory to have a qualitative picture of the modifications of the high and lowspeed streaks. Joint probability density function between vorticity and scalar gradients show how the bursting events affect the scalar distribution. Â© 2006 Springer.

Direct Numerical Simulations of turbulent channel flow with square bars on the bottom wall are discussed have been carried out at different Reynolds numbers. The results tend to confirm the inappropriateness of the roughness function as an indication of the effect a particular roughness geometry exerts on the flow. Distributions of turbulent intensities support the improvement in global isotropy relative to a smoothwall.

Motions that are responsible for the production and maintenance of the Reynolds shear stress in a turbulent boundary layer may be affected by the Reynolds number and the surface roughness. Evidence for each of these effects is presented, based mainly on experiments carried out in our laboratory. The effects are felt in both inner and outer regions of the layer. The evidence points to the nonuniversality of the active motion and to the sensitivity of the large scale motion to boundary conditions.

Statistics of Â¿u/Â¿y have been measured in a turbulent boundary layer over either a smooth wall or a riblet surface using parallel hot wires. Over the riblets, the mean square value of Â¿u/Â¿y (normalised with smooth wall variables) is smaller than over the smooth wall; the difference increases as the distance to the wall decreases. Also this difference is larger when the riblets operate in a dragaugmenting mode. These changes would reflect changes in the nearwall turbulence structure. Furthermore, on the basis that Â¿u/Â¿y is a major contributor to the spanwise vorticity, the results indicate that, relative to the smooth wall, the mean square spanwise vorticity is reduced near a riblet surface.

The smallscale structure of turbulence is studied by measuring the statistics associated with Â¿u/Â¿y in the turbulent wake behind a circular cylinder for a moderate range of RÂ¿ (60250). The results indicate both similarities and differences between the statistics of Â¿u/Â¿y and those of Â¿u/Â¿x. The pdf of Â¿u/Â¿y, like that of Â¿u/Â¿x, has long exponential tails which are Reynolds number dependent. The flatness factor of Â¿u/Â¿y is larger than that of Â¿u/Â¿x, implying that Â¿u/Â¿y is more intermittent than Â¿u/Â¿x. The spectrum of (Â¿u/Â¿y)2 does not exhibit any inertial range powerlaw dependence, a behaviour which has previously been observed in the spectra of (Â¿u/Â¿x)2. In the inertial range, the autocorrelation of Â¿u/Â¿y displays a r4/3 behaviour while the autocorrelation of (Â¿u/Â¿y)2 is similar to that of (Â¿u/Â¿x)2, both yielding the same value for the intermittency exponent Âµ.

Measurements have been made in a zero pressure gradient turbulent boundary layer in an attempt to quantify the influence of Reynolds number on features of the motion, which is organised on a scale comparable to the thickness of the layer, in the plane of main shear. These features have been obtained with an array of eight Xprobes aligned in a direction normal to the wall, each probe measuring velocity fluctuations u (streamwise direction) and v (normal to the wall). Information derived from the u and v data includes conventional spacetime velocity correlations, instantaneous and conditional particle paths and spanwise vorticity contours. The effect of Reynolds number on the spatial extent of isocorrelation contours is more important for u than v. No significant dependence on Reynolds number is observed for conditional particle paths but contours of conditional spanwise vorticity extend to a larger normalised distance from the wall at small Reynolds number. Contributions of the organised motion to the Reynolds stresses tend to be more important as the Reynolds number decreases.

The quadrant analysis technique of Willmarth and Lu (1972) has been used to estimate contributions from the four quadrants to the average momentum and heat transfers in the selfpreserving region of a turbulent wake. The importance of sweeps near the wake centreline and of ejections at the edge of the wake becomes clearer when sweeps and ejections are viewed in the context of the topology of the large scale motion. The application of the quadrant analysis to the products of velocity and temperature fluctuations conditioned on the large scale motion, clarified the picture inferred from the conventional quadrant analysis approach by clearly identifying the regions of space which are important for transferring momentum and heat.

A technique is presented for the computer detection of temperature fronts in a turbulent shear flow. The detection variable is the product, averaged over a given duration, of temperature fluctuations at a given number of spatial locations. Efficient algorithms are developed for computing the product and for determining accurately the instants of detection, aided by simulations, using model temperature fronts. Ensemble averages of temperature and velocity are obtained for the selfpreserving region of a turbulent plane jet. Â© 1986.

The similarity between velocity and temperature fields in the selfpreserving region of a plane jet is examined by considering spatial contours of ensemble averages of quantities formed using velocity u and v and temperature theta fluctuations. These averages were conditioned on the occurrence of temperature fronts observed with the use of a spanwise rake of temperature sensors. Reasonable similarity exists between overall correlation coefficients for u and v and for v and theta . There is also similarity between contributions from the random motion to these coefficients but, in this case, the spatial distribution is quite different than when the coherent contribution is included. Contributions to the Reynolds shear stress, temperature variance and lateral heat flux from coherent and random motions are roughly equal. The random motion makes a significantly larger contribution to the Reynolds normal stresses than does the random motion.

Thermal wake measurements have been made behind single hot wires, both well away from and very close to a conducting wall. Comparison with theoretical distributions highlights the transition from a two to a three dimensional wake as the distance from the wire increases. In the absence of a suitable theory, the measurements in wall proximity were analysed using enthalpy balances. The results provide a firm demonstration of the significant heat transfer to the wall that accompanies wall proximity. An implication of the theory, that wall proximity can be correlated using the wire heat transfer rate, is shown to have some experimental support.

The three components of the average temperature dissipation have been measured using a pair of parallel cold wires, in an approximately selfpreserving thermal layer. Mean squared values OVER BAR theta OVER BAR **2//,//y and OVER BAR theta OVER BAR **2//,//z of temperature derivatives in the directions normal to the flow were mainly obtained from the curvature of spatial temperature autocorrelations. The mean squared value OVER BAR theta OVER BAR **2//,//x of the temperature derivative in the flow direction was mainly inferred from the temporal derivative of temperature and Taylor's hypothesis after the latter was verified at a few locations in the flow. A measure of the accuracy of the dissipation measurements is provided by the negligible imbalance in the temperature variance budget measured in the outer flow region.

Measurements of the thermal wakes behind single hotwires have been made in both the freestream above a boundary layer and in the region adjacent to the surface where the measured mean velocity rises above that given by the sublayer equation. The former results show that enthalpy balances within the wake are accurate to within 20%. As the hotwire is moved toward the wall the much larger reduction in the enthalpy flux indicates a significant heat transfer to the aluminium wall. The concomitant increase in the measured mean velocity appears to be a function of the wire heat transfer rate, at least when the direct effects of the wire diameter can be ignored.

Twopoint correlations of temperature fluctuations confirm the existence, in the selfpreserving region of a plane jet, of spanwise structures, occurring alternately on opposite sides of the centreline. Conditional averages of temperature fluctuations are computed using a selection procedure based on information obtained at several points in space. The averages are compared with those obtained when the selection is based on information at one point in space.

The technique of K. N. Rao, R. Narasimha and Badri Narayanan (1971) is tested by applying it to both Gaussian noise and turbulent velocity fluctuation signals. Measurements include the dependences of the pulse frequency and intermittency factor on the magnitude of the threshold and the dependence of the maximum pulse frequency on the centre frequency of the filter. Important differences exist between white noise and turbulent signal distributions. These differences persist when the white noise spectrum is shaped in an attempt to simulate the spectrum of the turbulent velocity fluctuation. Refs.

The exact transport equation for the dissipation or destruction of temperature fluctuations in a steady, twodimensional shear flow is briefly discussed from the point of view of the experimenter's ability to measure the important terms. The transport equation for only one component of the destruction, the meansquare streamwise temperature derivative, is considered in more detail. Measurements of several terms of this equation have been made in the selfpreserving region of a turbulent plane jet.

A detailed accuracy analysis is presented for moments, up to order four, of both velocity (horizontal u and vertical w) and scalar (temperature Â¿ and humidity q) fluctuations, as well as of the products uw, wÂ¿ and wq, in the atmospheric surface layer. The highorder moments and integral time scales required for this analysis are evaluated from data obtained at a height of about 5 m above the ocean surface under stability conditions corresponding to Z/L \ 0.05. Measured moments and probability density functions of some of the individual fluctuations show departures from Gaussianity, but these are sufficiently small to enable good estimates to be obtained using Gaussian instead of measured moments. For the products, the assumption of joint Gaussianity for individual fluctuations provides a reasonable, though somewhat conservative, estimate for the integration times required. The concept of Reynolds number similarity implies that differences in integration time requirements for flows at different Reynolds numbers arise exclusively from differences in integral time scales. A first approximation to the integral time scales relevant to atmospheric flows is presented. Â© 1978 D. Reidel Publishing Company.

The optical refractive index fluctuation has been determined from measurements of turbulent temperature and humidity fluctuations in the atmospheric surface layer over the ocean. Probability density, spectral density and even and oddorder structure functions of the refractive index fluctuation are presented. The spectral density exhibits a significant '5/3' inertial subrange as a result of the existence of a '5/3' subrange in the spectra of temperature and humidity fluctuations and in the temperaturehumidity cospectrum. The behaviour in the inertial subrange of fourth and sixthorder structure functions of the refractive index is in reasonable agreement with that predicted by the analysis of Antonia and Van Atta (1975, 1978). The thirdorder structure functions of the refractive index exhibit an approximately linear dependence on separation in the inertial subrange, in agreement with a ramp model for the large coherent structure of the motion.

Measured spectra of Â¿ x, Â¿ y, Â¿ z, the derivatives of temperature in streamwise, lateral and vertical directions, respectively, indicate that the spectral densities of Â¿ z and Â¿ y are nearly similar but significantly different from the spectral density of Â¿ x. The highfrequency parts of the three spectra satisfy, in a qualitative sense, local isotropy requirements. In the highfrequency end of the inertial subrange, the relative behaviour of spectra of Â¿ x, Â¿ y and Â¿ z is also consistent with local isotropy. Â© 1978 D. Reidel Publishing Company.

Ensemble average shapes of temperature Â¿ and vertical velocity w associated with a 'ramplike' signature of the temperature signal recorded in the marine surface layer have been obtained with the use of a conditional sampling technique. The resulting shapes support the 'ramplike' description of temperature and also suggest an approximately linear distribution in the case of w. The sharp decrease in temperature at the upwind end of the ramp coincides with a relatively sharp decrease in vertical velocity. The region of the ramp in the vicinity of the sharp temperature decrease makes a large contribution to the average heat flux in the layer. Â© 1978 D. Reidel Publishing Company.

Horizontal u and vertical w velocity fluctuations have been measured together with temperature Â¿ fluctuations in the atmospheric surface layer, at a small height above a wheat crop canopy. Marginal probability density functions are presented for both individual fluctuations u, w, Â¿ and for the instantaneous Reynolds stress uw, and heat fluxes wÂ¿ and uÂ¿. Probability density functions of the velocity fluctuations deviate less significantly from the Gaussian form than the probability density of temperature. There appears to be closer similarity between statistics of the instantaneous heat fluxes than between the momentum flux and either of the heat fluxes investigated. The mean momentum flux receives equal contributions from the events referred to as 'ejections' and 'sweeps' in laboratory boundary layers. 'Sweeps' provide the largest contribution to the heat fluxes. Â© 1977 D. Reidel Publishing Company.

Temperature fluctuations in a turbulent shear flow are modeled by a ramplike signal on which relatively high frequency Gaussian fluctuations are superimposed. Both linear ramps with fixed height and length and exponential ramps of variable length are considered. Parameters which characterize the exponential ramps are obtained from experimental data in a heated jet. High order moments of temperature calculated with the use of the ramp model are in reasonable agreement with available experimental measurements. Copyright & 1976 American Institute of Physics.

The burst frequency or frequency of regions in a turbulent flow where the energy dissipation is large has been measured in both laboratory and atmospheric shear flows. The laboratory measurements were made in two slightly heated flows, a boundary layer in zero pressure gradient and an axisymmetric jet with a coflowing external system. The atmospheric data were obtained in the first few meters above a wheat canopy. For the laboratory data, the burst frequency, as determined from either velocity or temperature signals, is found to be approximately equal to one half the zero crossing frequency of these signals. In the atmosphere, the burst frequency is very roughly twice the zero crossing frequency. The burst intermittency factor and the ratio of the bunt width to Kolmogoroff length scale are found to be very weakly dependent on the Reynolds number. Available data in the literature on the intermittency factor and width of bursts exhibit extensive scatter and conflicting Reynolds number trends. Copyright Â© 1976 American Institute of Physics.

Measurements are presented of both mean and fluctuating velocity components in a turbulent boundary layer subjected to a nearly homogeneous external turbulent shear flow. The Reynolds shear stress in the external shear flow is small compared with the wall shear stress. Its transverse mean velocity gradient Â¿ (Â¿ 6 sl) is also small compared with typical gradients based on outer variables (say Uw/d, where Uwis the value of the linear velocity profile extrapolated to the wall and d is the boundarylayer thickness), but is of the same order as Ut/d (Ur is the friction velocity). The influence of both positive and negative transverse velocity gradients on the turbulent wall layer is investigated over a streamwise region where the normal Reynolds stresses in the external flow are approximately equal and constant in the streamwise direction. In this region, the integral length scale of the external flow is of the same order of magnitude as that of the wall layer. Measurements in the boundary layer are also given for an unsheared external turbulent flow (Â¿ = 0) with a turbulence level Tu of 1.5%, approximately the same as that for h = Â± 6 s1. (Tu, is defined as the ratio of the r.m.s. longitudinal velocity fluctuation to Uw.) The measurements are in good agreement with those available in the literature for a similar freestream turbulence level and show that the external turbulence level and length scale exert a large influence on the turbulence structure in the boundary layer. The additional effect of the external shear on the mean velocity and turbulent energy budget distributions in the inner region of the boundary layer is found to be small. In the outer region, the Â¿wakeÂ¿ component of the mean velocity defect is lowered by the presence of freestream turbulence and one extra effect due to the external shear is an increase in the Reynolds shear stress when h is positive and a decrease when h is negative. Another interesting effect due to the shear is the appearance near the edge of the layer of a small but distinct region where the local mean velocity is constant and the Reynolds shear stress is negligible.
