A mathematical model for combustion of N powder with added aluminum particles is presented. It takes account of the exothermal chemical reaction in the gas phase, convection and diffusion, heating, and combustion of aluminum particles in the gas flow, the motion of combustion products, and the lag of the particle velocity behind that of the gas. The results of calculation of the burning velocity of powder correspond to the experimental data on the dependence of this velocity on pressure and aluminum particle size. It has been established computationally that for aluminum particles of diameter less than 20 μm the burning velocity of N powder depends substantially on the size of these particles.
