DYNAMICS OF A VARIABLE IN WIDTH GAS SUSPENSION LAYER ACCELERATED BY A PASSING SHOCK WAVE
Using the hybrid large-particle method, the regularities of the interaction of a shock wave when it impacts a gas suspension layer with curved boundaries are studied. Two-dimensional effects of double von Neumann refraction, focusing or divergence of the refracted shock wave, and baroclinic instabil...

description | Using the hybrid large-particle method, the regularities of the interaction of a shock wave when it impacts a gas suspension layer with curved boundaries are studied. Two-dimensional effects of double von Neumann refraction, focusing or divergence of the refracted shock wave, and baroclinic instability at the gas-suspension interface with the formation of mushroom-shaped or ring-shaped vortex structures are established. The features of the nonequilibrium flow are identified. These features associated with a decrease in the intensity of the passing shock wave and the splitting of the initial separation of the media into two contact discontinuities – a jump in porosity and a contact discontinuity in the gas phase |
