Abstract

The authors construct a mathematical model for the adiabatic heterogeneous detonation and detonation wave propagation of a suspension of fuel droplets in gas under the influence of nonequilibrium in the two-phase flow. The nonideality of the model results in difficulties in the selection of the detonation velocity and the location of the Chapman-Jouguet plane. The following rules are proposed for the selection of the Chapman-Jouguet plane location: the site of complete drop burnup; the plane of drop shattering and ignition; equality of the Mach numbers; utilization of approximate chemical equilibrium; using boundary conditions for the gradients in the reaction zone; and dependence on the relationship between the characteristic relaxation times of the phase velocities, the heat transfer between the phases and the heat liberation, by one of four possible equilibrium-frozen speeds of sound.
