Explosion and Detonation Characteristics of Silane- and Propylene-based Mixtures

Approximate two-step models of chemical kinetics of detonation combustion in silane- and propylene-based mixtures are presented. They include one differential equation for the calculation of molar mass of the mixtures after induction period (in the main heat release zone) and algebraic formulas for calculation of the internal energy, heat release, heat capacities and adiabatic index of the mixtures. The models correspond to the second law of thermodynamic and Le Chatelier's principle. They are simple and high accurate and therefore can be used in one- and multi-dimensional numerical calculations of detonation and explosion processes in corresponding gaseous mixtures. Based on these models the structures of DW and equilibrium parameters of the considered mixtures were obtained.
