Abstract

Abstract: 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. Highlights: The interaction of Prandtl–Meyer flow with quasi-one-dimensional streams was studied. Results of the study can be used in supersonic jet flows–obstacle interaction analysis. The interaction studied also presents in other supersonic flows with Mach reflection. Interaction of supersonic jets with launch system influences the safety of space vehicle launch.
