Abstract

Theoretical study of receptivity of a thin weakly non-parallel shock layer to acoustic disturbances is performed. We apply the general theory of boundary layer receptivity to the case of shock layer eigen modes excited by the impinging acoustic wave. The spectrum of eigen modes is obtained in analytical form in the thin shock layer approximation, assuming the flow inside the shock layer is uniform. This allows to predict the effective directions of an impinging acoustic wave that cause resonance with the eigen modes, as well as locate the regions of the shock layer where the resonance is taking place.
