Abstract
The combustion of a mixed metallized solid fuel containing boron particles is numerically studied. The mathematical model is based on the approaches of two-phase reacting medium mechanics for describing processes in a two-phase flow above the fuel surface and the Hermance model for describing the decomposition of a mixed solid fuel. The model of combustion of a mixed metalized solid fuel takes into account the oxidation and combustion of boron particles. The dependence of the burning rate of a metallized mixed solid fuel on the gas pressure above the combustion surface and the size of boron particles is determined from a parametric study.
