“…It should be emphasized that the layer in our case originated near the contact discontinuity. A similar result was obtained in [13], where the problem of propagation of decaying spherical shock waves generated by an explosion of the central charge was considered. The motion of fine particles in the gas flow field without allowance for the particle influence on the gas was considered.…”

The problem of shock-wave transition past a backward-facing step in a gas suspension is solved. The calculation method is tested on a similar problem for a pure gas, and good agreement with available experimental and numerical results is reached. The effect of shock-wave intensity, mass load factor of particles in the mixture, and particle size on the flow structure in the gas suspension is determined. It is shown that the greatest difference between the flow pattern in a two-phase mixture and the corresponding flow in a pure gas is observed in the range of times when the characteristic sizes of the structures being formed are commensurable with the scale of the relaxation zones.
