Effect of side walls on the supersonic ramp flow structure

Abstract

The reattachment zone structure of a supersonic separated ramp flow was experimentally studied at M∞ = 6. Several ramp model configurations with and without side walls were considered. It was found that the geometric size of streamwise vortices in the reattachment zone increases due to the absence of transverse flow in the separation region. Moreover, flow separation regions were detected on the model side walls which interact with the ramp-induced separation region, forming corner vortex structures.
