| Abstract: | When a planar shock wave is sweeping a density layer, the deformation of the density interface and the wave configurations can occur Numerical simulations about this process for high density layer is proposed The result based on TVD scheme is checked using analytical simulations, It shows that the interaction of the shock wave with the high density layer can induce the wave reflection from the wall which is either a stationary regular reflection or a stationary Mach reflection |
