Abstract The interaction between oblique shock and preceding expansion or compression Prandtl–Meyer wave of the same direction are studied theoretically. Two reliable analytical solutions for overtaking Prandtl–Meyer wave–oblique shock interaction were obtained. The criteria of reflected wave type change, shock inflection and degeneration, occurrence of subsonic flow pockets and influence of ratio of gas specific heats are established analytically. The results obtained can be used for the design of re-entry capsules, supersonic inlets, and supersonic nozzles, where wave interactions considered in the present paper take place.
Highlights Analytical models are proposed for Prandtl–Meyer wave overtaking oblique shock interaction in supersonic flow. Criterion was derived qualifying different flow patterns arising in wave interaction. The influence of gas specific heats ratio on the obtained solutions was analyzed.
