Wave processes occuring in supersonic motion of blunted body through dust layer

Numerical simulation is made of unsteady structure of a two‐phase shock layer in front of a sphere flying through a dusted region. Effect of the dispersed particles rebounded by the sphere surface is taken into account. Simulation is based on modified Eulerian‐Lagrangian (E‐L) description of the two‐phase flow. Analysis shows that in the case under study the structure of the shock layer is characterized by the dispersed phase concentration fronts and internal pressure jumps interaction with the bow shock and the sphere surface. It is shown that when the sphere enters the dust layer the surface heat flux and friction increase significantly.
