We analysed existing approaches to simulating ignition and combustion processes in powdered metal fuels. The study considers a mathematical model of an aluminium particle aerosol and suggests a new finite difference scheme for solving a system of differential systems numerically. We show good convergence between the computation results we obtained and the data presented in the publication [1].
