INTERACTION OF A PLANE SHOCK WAVE WITH REGIONS OF VARYING SHAPE AND DENSITY IN A FINELY DIVIDED GAS SUSPENSION

A study has been made of the interaction between a plane shock wave in a gas or a gas suspension and regions of square and rhombiform cross sections differing from the environment in density. A high-stability monotonic scheme with small numerical dissipation was used for calculation. Comparisons with experiments on the refraction of the shock wave on the interface of a binary gas have confi rmed the adequacy of the scheme. The infl uence of the densityratio factor (Atwood number), the shape of inhomogeneities, and the particle size on the shock wave structure and the development of a Richtmyer–Meshkov instability has been shown
