The purpose of this research was to investigate the spatial structure of a two-phase flow in a supersonic model channel of circular cross-section with a diameter of the cylindrical part of ~10 mm. For modeling, we used the Euler-Lagrange approach in combination with a probabilistic estimate of the dispersed particles deviation from their base trajectory. Chromium-nickel alloy particles with a diameter of 15 to 40 μm move in the channel in a special way, which was considered in the paper. Furthermore, we analyzed how the nature of the distribution function of the particle’s root-mean-square deviation from its base trajectory influences the quality of mixing of the dispersed phase with the flow and the number of particles interacting with the walls of the flow path.
