Compressible Mixing Layers with and without Particles
Abstract
An extensive experimental research program has been carried out to explore the effects of compressibility in high Reynolds number turbulent free mixing layers. Three mixing layers with convective Mach numbers of 0.51 (Case 1) , 0.64 (Case 3), and 0.86 (Case 2) were investigated. While Case 1 marks the onset of the compressibility effect on the mixing layer growth rate, the vorticity growth rate of Case 3 is approximately 50% less than that of an incompressible mixing layer with the same velocity ratio. Various experimental techniques such as laser Doppler velocimetry, two-point space-time correlations, filtered Rayleigh scattering based flow visualizations, and conventional laser sheet lighting have been utilized.
