STRUCTURE OF THE HETEROGENEOUS DETONATION OF ALUMINUM PARTICLES DISPERSED IN OXYGEN

Mathematical models of the integral and local parameters of the heterogeneous detonation of aerosuspensions are reviewed. The problem of the detonation of a mixture of aluminum particles and oxygen and the action of the burning gas-suspension volume on the surrounding medium is formulated in the framework of nonequilibrium one-dimensional nonsteady flow. Steady flows of aluminum-oxygen gas suspensions are analyzed; the theoretical dependence of the detonation rate on the particle content agrees satisfactorily with the experimental data.
