Features of an underexpanded pulsed impact gas-dispersed jet with a high particle concentration

We have reported on the results of a numerical simulation of the inflow of an underexpanded pulsed gas-dispersed jet with a high particle concentration onto a rigid obstacle unbounded in the transverse direction. The characteristic features of such interaction, in particular, the anomalous formation of the shock-wave structure of the two-phase flow at the subsonic velocity of the carrier gas and the evolution of self-sustained oscillations, have been investigated.
