Mach 5 experiments were conducted to understand the flow physics of micro-vortex generators and their ability to suppress separation from shock wave-boundary layer interactions. From pressure measurements, the micro-ramps delayed the upstream pressure rise, an indication of boundary layer separation suppression. The complex flow structures were recorded using qualitative techniques.
