ON ONE CASE OF INTERACTION OF STATIONARY PLANE OBLIQUE SHOCK WAVES IN A POLYTROPIC GAS

The interaction of plane oblique shock waves, one of which overtakes the other, at an arbitrary angle in a polytropic gas with a constant polytropic index has been considered in the context of the hydrodynamic theory of shock waves. The pattern of the decay of a discontinuity arising in this case and the dependence of its dynamics on the angle of interaction of the waves have been investigated on the basis of numerical calculations. The characteristic angles at which a shock-wave configuration develops and their dependence on the velocity of initial shock waves have been determined.
