The shock wave schematization in the 2D inviscid and viscous heat conducting flows

Within the framework of model of the ideal perfect gas, the steady supersonic gasdynamic flows with many discontinuities are simulated. The method with not connected grid is applied. The adduced calculations demonstrate the high resolving power and efficiency of the given method. Within the framework of model of the viscous heat conducting perfect gas (large Reynolds numbers) as main (basic), the steady problem about interaction of a shock wave with a shift layer is considered. The shock (discontinuity) thus also schematized, and the factor of viscosity - heat conduction is taken into account in usual and in differential relations. The analytical solution (in the extended sense) of a problem of penetration of a shock wave into the shift layer is received. Difference in behavior of shock waves of the large and small intensity is shown.
