| Abstract: | A study is made of the combined effect of a high-velocity two-phase (gas—solid particles) flow to the surface of a body. Different ablation models are proposed for simultaneous thermal (or thermochemical) and impact influence of the flow on the material. A numerical investigation is made of the unsteady thermal state of a body on which solid particles impinge, and the ranges of the determining parameters in which the thermal effect is negligibly small compared with the erosive effect are determined.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 120–126, January–February, 1984. |
