Abstract

The paper deals with the problem of the 1D and 2D structures of detonation waves (DW) in the silane-air mixture within the framework of mathematical model of a nonequilibrium gas dynamics. Detailed kinetics scheme of silane oxidation as well as the newly developed reduced kinetic model of detonation combustion of silane are used. On its basis the DW structure in stoichiometric silane - air mixture and dependences of Chapman-Jouguet parameters of mixture on stoichiometric ratio between the fuel (silane) and an oxidizer (air) were obtained. It was revealed that in the reaction zone, in the structure of DW, the heat release in the model with detailed kinetics is non-monotonic.
