Extreme Triple Configurations with Negative Slope Angle of the Reflected Shock

Resumo

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