Abstract
Abstract
A simple model of reduced kinetics is proposed to describe the detonation combustion of gas particle suspensions with a non-uniform concentration distribution. The model is verified on the basis of empirical data on the dependence of the detonation velocity on the particle loading. The model constants for the substoichiometric and superstoichiometric suspensions of aluminum particles in oxygen are determined. The formation of suboxides and incomplete combustion of aluminum are taken into account integrally. Examples of numerical simulation of the Chapman-Jouguet detonation propagation in mixtures with longitudinal concentration gradients and cellular detonation in lean and superstoichiometric mixtures of aluminum and oxygen are presented.
