Abstract
We have numerically simulated the interaction of a shock wave with a convex double angle within the framework of a model of inviscid non-heat-conducting gas. The main attention is paid to the stage of a two-shock diffraction configuration on the second face of the wedge. Special features of flow under various condi-tions of diffraction are revealed. We also propose an explanation of the appearance and behavior of a purely gasdynamic layer formally resembling the viscous boundary layer.
