e time variation of a particular fluid property . in the fluid. It has largely superseded the earlier hot film probes or thermistors, which were used to obtain similar information, with the recognised risk that the very presence of the probe might itself modify the flow.

Chaminda Chandrasekara,Pushpa Herathied. The pressure-strain correlations, which are responsible for the intercomponent energy transfer were estimated from other turbulence statistics. High accuracy in the determination of these was ensured by use of an angle calibration technique for the hot-wires. The degree of anisotropy of the dis

Chaminda Chandrasekara,Pushpa Herathof flow instability mechanisms. After the initial roll up of the shed vortex sheet into discrete vortices, the most common interaction that a shear layer undergoes is pairing of two neighboring vortices. The pairing process, . the growth of the subharmonic, is a consequence of what has come to be kn

Chaminda Chandrasekara,Pushpa Heratherimposed random fine scale turbulence. However, in a region further downstream, the phase of the passing coherent structures becomes decorrelated and random small eddies occur. In this paper, the physical mechanisms of these transition processes are discussed.

Chaminda Chandrasekara,Pushpa Herathermittency in stochastic models of global spectral dynamics, first elucidated by Kolmogorov (1962), remains a major point of difficulty (Chen .. 1989). More recently, there is growing interest in the role of intermittency in scale similarity as described by multifractal geometry (Sreenivasan & Menev

Chaminda Chandrasekara,Pushpa Herathted as a steady profile modified by a time function. The analysis resulted in a perturbation of the stream function that is similar to that under steady conditions but over a stretched time variable. Solis (1986) showed that in the case where the variation of the mean flow is periodic, the instabili
