Optimal triple configurations of stationary shocks

Abstract

The triple configurations of stationary shock waves with negative slope angle of the reflected shock to the velocity vector of the supersonic stream before the triple point (“inverse” triple configurations) are considered. “Inverse” configurations with maximum relations of flow parameters at the slipstream after triple point are determined. Extreme relations of the flow parameters downstream the “inverse” configurations are compared with the parameters achieved on the whole set of the triple-shock configurations that appear in supersonic streams of the inviscid perfect gas.
