Mathematical simulation of shock waves processes in chemical inert and reacting polydisperse mixtures of gas and solid particles

The set of integro-differential equations of motion of polydispersed inert and reacting gas particle suspension with continuns distribution of particle size spectrum is presented. The procedure of numerical solution of these equatoins by the coarse-particle method is described. The numerical investigation of the process of interaction of shock wave with the layer of polydispersed inert gas-particle suspension is made. The influence of the function of size particle distribution on the regularities of attenuation of front of shock wave in gas-particle suspension is analysed. The numerical simulation of the process of shock initiation of heterogeneous detonation in gas-particle suspension of propellent is studied. The influence of particle size spectrum on the regularities of formation of combustion and detonation waves in reacting gas-particle mixtures is shown.
