Abstract

Under certain conditions, high speed flow over closed cavities becomes unstable, leading to large flow flucuations inside and around the cavities. This phenomenon is simulated for a 1.5-inch deep by three-inch long cavity using a water table. Upstream blowing is used in an attempt to supress the oscillations.

Steady blowing produced total attenuation. Pulsed blowing produces similar attenuation for a few cycles, and then excited the oscillations to higher amplitude.
