The compressible shear layer over a two-dimensional cavity

Research output: Contribution to conference › Paper › peer-review

Abstract

Single and double-pulsed planar laser Mie scattering from condensed ethanol particles was used to visualize the compressible shear layer over a closed cavity at Mach numbers of 1.8, 2.0, 2.7, and 3.5. Spatial correlations based on large ensembles of the resultant images were used to track structures in the shear layer above the cavity, and thus quantify convective velocities, and structure size, shape, and orientation. Structures were found to be significantly smaller and less organized at higher Mach numbers. The structures were oriented more nearly parallel to the flow at higher Mach numbers.
