Abstract

This paper presents results on the numerical solution of the flame propagation problem in the air with suspended aluminum and boron particles. The aim of the study is to determine the combustion rate of the Al-B-air mixture depending on the particle mass concentration and its size. The physical and mathematical model of the process is based on the approaches of the mechanics of two-phase reactive media. The numerical method for solving the problem is based on the decay algorithm of an arbitrary discontinuity. It is shown that the apparent burning rate of the aerosol suspension of the mixture of aluminum and boron powders slightly decreases with an increase in the mass fraction of the powder in the mixture.
