Recent experimental results describing the vortical structure of the mixing layer are reviewed. The largest turbulent features are quasi two-dimensional vortices aligned along the span of the flow. As a result of interactions, the vortices rapidly develop an invariant space-time geometry. Superimposed on this vortex structure are smaller scales which include longitudinal vortices of size comparable to the Taylor microscale, and smaller scales which considerably enhance molecular mixing. These smaller scales coexist with the quasi two dimensional structure. At present, no theoretical framework is available to describe the geometrical features of these complex shear flows.

Results of an experimental study of turbulent mixing between two streams of different density are summarized. The effects of density difference in flows at low Mach number are compared to those due to compressibility effects at high Mach number. The mixing layer at low Mach number is examined for large vortex structures. (Author).

Turbulence, mixing and the mutual interaction of turbulence and chemistry continue to remain perplexing and impregnable in the fron tiers of fluid mechanics. The past ten years have brought enormous advances in computers and computational techniques on the one hand and in measurements and data processing on the other. The impact of such capabilities has led to a revolution both in the understanding of the structure of turbulence as well as in the predictive methods for application in technology. The early ideas on turbulence being an array of complicated phenomena and having some form of reasonably strong coherent struc ture have become well substantiated in recent experimental work. We are still at the very beginning of understanding all of the aspects of such coherence and of the possibilities of incorporating such structure into the analytical models for even those cases where the thin shear layer approximation may be valid. Nevertheless a distinguished body of "eddy chasers" has come into existence. The structure of mixing layers which has been studied for some years in terms of correlations and spectral analysis is also getting better understood. Both probability concepts such as intermittency and conditional sampling as well as the concept of large scale structure and the associated strain seem to indicate possibilities of distinguishing and synthesizing 'engulfment' and molecular mixing.

Experimental studies have been conducted in a curved mixing layer in which both the velocity ratio and the density ratio were variable. Flow visualization studies and profile measurements covered a wide range of experimental conditions. The structures observed experimentally were examined in the light of three different instability mechanisms which can exist in the same mean flow. For the case of mixing layers with uniform density, it was found that the normal large spanwise vortex structures can be weakened or inhibited by Taylor-Goertler instability if the inner stream is faster than the outer stream. For the case of mixing layers with different densities, three-dimensionality is greatly enhanced by Rayleigh-Taylor instability if the inner stream is heavier than the outer stream, and especially if the inner stream is also faster. In the former case the growth rate of the mixing layer was found to be insensitive to changes in the velocity ratio. The effects of curvature on the structure of the curved turbulent mixing layer were explored in terms of length scales and celerity for the large spanwise structures where these structures could be observed. Other things being equal, the celerity of the large structres was found to depend on density ratio and velocity ratio but not on the sense of the mean streamline curvature. (Author).
