Mathematical Modeling of Combustion of a Mixture of Ultradisperse Aluminum Powder with Water

The authors present a physicomathematical model of combustion of a mixed solid fuel in the form of a mixture of ultradisperse aluminum powder with gel-like water. The model takes account of the combustion of aluminum particles in steam, the motion of combustion products, and the lag of the velocity of motion of the particles behind that of the gas. The results of calculating the combustion rate are consistent with experimental data on the dependence of the rate of combustion of the mixture of ultradisperse aluminum powder with water on pressure.
