Mathematical modeling of the dynamics of slagging and thermochemical destruction of carbon composite thermal protective materials in a high-temperature two-phase flow

A new complex physicomathematical model, a numerical algorithm, and a computational program are developed for the calculation of the dynamics of slagging and thermochemical destruction of carbon composite thermal protective materials of multilayer walls in a subsonic high-temperature two-phase flow with inertial precipitation of polydisperse liquid particles of metal oxides in cycles of heating and cooling (aftereffect). The results of a numerical study of the thermal and chemical effects of inertially precipitated liquid aluminum oxide particles on the heating and ablation parameters of a typical thermally reactive pressed carbon composite in one cycle of heating and cooling of a two-layer wall of the channel in a power plant are given.
