Numerical simulation of characteristics of supersonic jet interaction flowfields

The interaction flowfields induced by lateral supersonic single jet mounted on a flat plate had been described by numerical simulation in this paper. The method was validated by experimental results, including the pressure distributions around the jet; and schlieren photo in which the shock wave structures had been expressed; and the oil flow pattern which shown the separation region. The surface and spatial structures of interaction flowfields are revealed in detail. The influences of pressure ratio on the structures and characteristics are analyzed.
