Interaction of a shock wave with a tangential discontinuity

Journal of engineering physics Aims and scope

Abstract

The interaction of the shock wave receding from an obstacle with the line of a tangential discontinuity is investigated for unrated supersonic jets. It is suggested that one of the causes of strong instability of the wave structure of the jet at certain positions of the obstacle may be the incompatibility of conditions from different sides of the tangential discontinuity at the intersection of the latter with the shock wave.
