The interaction of a Prandtl-Meyer wave and a quasi-one-dimensional flow region

A mathematical model for the interaction between a Prandtl-Meyer flow and a quasi-one-dimensional subsonic or supersonic stream is developed. The analytical description of the shape of the slipstream dividing two interacting streams is achieved, and its parametrical analysis is performed. The results of the study may be of practical use in supersonic jet flow-obstacle interaction analysis, which is important for the safety of space vehicle launches.
