On the Interaction Between the Shock Wave Attached to a Wedge and Freestream Disturbances
Abstract
We present a study of the interaction of small amplitude, unsteady, freestream disturbances with a shock wave induced by a wedge in supersonic flow. These disturbances may be acoustic waves, vorticity waves, or entropy waves (or indeed a combination of all three). Their interactions then generate behind the shock disturbances of all three classes, an aspect that is investigated in some detail, our motivation here being to investigate possible mechanisms for boundary-layer receptivity, caused through the amplification and modification of freestream turbulence through shock-body coupling. Also, the possibility of enhanced mixing owing to additional vorticity produced by the shock-body coupling is investigated.
