Simulation of combustion of solid high-energy materials with account for erosive effects

A negative erosive effect arises in the simulation of combustion due to a generated turbulent motion in the gasification zone of a solid energy material. A thermal energy in the gasification zone comprises the heat of chemical sources in it and the heat coming up to the gasification surface from the flame zone in a gaseous phase. Some of this energy returns to the gaseous phase in the form of the mechanical energy of turbulent motion, and this turbulence cools down the gasification zone. This model is used to explain the weakening of the negative erosive effect, observed in the experiments, with increasing pressure and decreasing initial temperature.
