Abstract

The receptivity of a boundary layer on a flat plate to acoustic disturbances in an incoming supersonic gas flow is studied numerically. Angles of attack are considered, at which shock waves and a rarefaction fanlike spread are generated in the flow field. The peculiarities of the interaction of these structures with acoustic waves have been studied, and regularities in the origin of the boundary layer instability region have been obtained.
