The structures of two opposed supersonic free jets with the same and different source pressures are studied by numerical simulation using the piecewise linear method (PLM) based on Godunov's method. For different source pressures, the ratio between the source pressures is set at 1.0 or 2.0. The ratio of the higher source pressure to the back pressure is varied between 50 and l00. The simulation results are analyzed and show agreement with the theoretical and experimetal results with respect to the flow field structures, internal structure of the interacting region and the positions of the shock waves. A dead air region is formed in the vicinity of the slip line. The flow field structure depends significantly on the pressure in the interacting region, where the pressures of the two jets balance.
