| Abstract: | The results of investigating shock-wave interaction with a particle cloud on the range of transonic relative velocities are
presented. Transition of the two-phase flow from the supersonic to the subsonic regime during phase velocity relaxation under
conditions of well-expressed gas-phase nonstationarity was observed. The effect of gas acceleration in the subsonic phase
interaction region, previously predicted by the authors on the basis of the accelerating screen model, is confirmed experimentally.
The presence of a substantial chaotic component of the particle longitudinal velocity, which indicates close internal phase
interactions of the collision type, is demonstrated.
