INTERACTION OF STATIONARY SHOCK WAVES WITH A BODY IN THE PRESENCE OF A CLOUD OF DISPERSED PARTICLES IN FRONT OF IT

Abstract

Within the assumptions of the mechanics of multiphase media, the interaction of stationary (infinite duration) shock waves with a transversely positioned plate in the presence of a shielding layer of gas suspension of dispersed particles in front of it is studied. The problem was solved numerically using the large particle method. Characteristic profiles of phase velocities in an incident shock wave are obtained, as well as calculated "oscillograms" of pressure and phase temperatures at fixed points on the front surface of the plate. The influence of the determining parameters on the maximum pressure on the plate and the intensity of particle runoff on its surface has been studied. It is noted that the presence of a dust layer in front of the body, depending on the mass content of the dispersed phase in it, can lead to both a decrease in maximum pressure and an increase in it. The outflow of particles to the plate surface increases with an increase in their size.
