| Abstract: | The interaction of a uniform hypersonic gas flow with a supersonic two-phase gas-particle source is considered. In the symmetry-axis
neighborhood between the bow and termination shock waves, an approximate analytical solution for the carrier-phase parameters
is found. On the basis of parametric numerical calculations, the behavior of the particle trajectories and the concentration
distribution in the shock layers are studied for both continuum and free-molecule flow regimes around the particles. The appearance
of regions with multiple intersections of the particle trajectories and the formation of "layer structures" in the particle
concentration distributions (particle accumulation regions near the envelopes of the particle trajectories) are indicated.
The dependence of the number of the high concentration layers on the governing parameters is studied.
