内容記述 | Interactions of the planar shock wave propagating along a backward-facing step region with a density interface are simulated numerically. The time-dependent solutions of the Euler equations were obtained by using a explicit predictor-corrector Total Variation Diminishing (TVD) scheme. A flow field consists of two regions, one is the backward-facing step region filled with gas-2, the other is the region filled with gas-1 above it. A planar shock propagating in gas-1 propagates along the backward-facing step and interacts with the interface separating these two gases with different densities. Two general cases of interface are considered, which are called as a slow/fast interface and a fast/slow interface. As parameters of calculations, a density ratio of two gases and a shock Mach number were selected. In the case of slow/fast interaction, a shock transmitted in a light gas propagates with higher propagation velocity and, behind the shock, a large vortex is created which mixes two gases. For the fast/slow interactions, a shock transmitted in a heavy gas forms an oblique shock wave whose angle is determined by the density ratio and the interface is more stable in comparison with slow/fast interaction. | |||||
