Mathematical Combustion Model of a Two-Component Gas Supension Including a Powder Combustible and a Powder Oxidizer

摘要

A mathematical model of the ignition and combustion of aluminum and ammonium perchlorate powders in a propulsion system that takes into account their polydisperse distribution and the difference between the gas and disperse-phase velocities and temperatures is developed. The effect of the pressure, the ratios between the components, and the dispersivity of aluminum particles on the structure of a gas-disperse flame, the basic characteristics of the combustion of a gas suspension, and the completeness of propellant combustion is studied.
