The interaction between a weak vortex and an otherwise normal shock wave was investigated in a Mach 2.49 flow. Measurements of the flow properties in the core region of the weak vortex indicated reduced total pressures, a wakelike axial Mach-number distribution and a Byrgers-like swirl profile. The measurements also showed a significant reduction of the axial Mach number in the vortex generator wake where the measured axial Mach number was found to be lower than that at the vortex axis. It was found that interaction of the weak vortex with a normal shock front revealed a local bulging of the shock wave in the upstream direction.
