The distribution of phase velocities of heterogeneous flow in the neighborhood of the stagnation point of a blunt body

The paper gives the results of experimental investigation of the velocities of both phases of heterogeneous flow in the neighborhood of the stagnation point of a blunt body with a hemispherical end face. The distribution of the velocities of "pure" air, of incident particles, and of particles reflected from the body is measured. The resultant data are necessary for constructing mathematical models of flows of gas with solid particles which intensively interact both with the model surface and with one another.
