Abstract

A new mathematical model of the hot spot reaction and evolution of the liquid agglomerate of metal oxides on the surface of charring thermal protective materials of multilayer walls is proposed. Within the framework of a local one-dimensional model, a parametric computer simulation has been carried out of the unsteady heating and mass ablation in the chemical hot spot reaction of the gas-liquid agglomerate of the condensed aluminum oxide phase with a rubberlike thermal protective material under the characteristic conditions of stagnation zones in a high-temperature two-phase medium.
