| Popis: | A theoretical and experimental study was undertaken of the problems of shock wave propagation in heterogeneous media containing an oxidant in the gaseous phase and a fuel in the condensed phase. The fuel was in the form of dispersed droplets in the flow of oxidant or in the form of a thin film on the wall of a tube. A system of governing equations with boundary conditions is composed that makes it possible to simulate numerically the initiation of detonation and the acceleration and slowing down of an unsteady wave to a self-sustaining regime. To verify the mathematical model, experiments were carried out in a shock tube for pure gas, for inert model, experiments were carried out in a shock tube for pure gas, for inert dispersed droplets, and for combustible dispersed droplets. The comparison of the results shows good agreement of theoretical and experimental data. |
