Abstract

Influence of externally forced initial flow conditions on axisymmetric cavity shear layer were studied. A sinusoidally heated strip upstream of the cavity excited Tollmien-Schlichting waves which, after amplification by the boundary layer, were introduced to the cavity shear layer. By choosing forcing frequencies within the range of shear layer receptivity, it was possible to control frequency and amplitude of the oscillations and consequently control the cavity drag.
