Abstract

An analysis is carried out to study influence of heterogeneous incident flow poly dispersity on thermo-erosive destruction for heat-protection materials. Obtained results indicate possible interference between temperature fields under the influence of various-sized particles. It is shown that incorporation of smaller particles into heterogeneous flow carrying large particles causes a reduction oj total destruction speed for the heat-protection material.
