Other AbstractIn this paper, the influences of specific heat ratio, the modification term in the detailed reaction kinetics, and the activation energy on the properties of chemical reaction kinetics of detonation models are studied. The results first demonstrate that the temperature power function to modify the chemical reaction rates of detailed chemical reaction kinetics should be replaced by a temperature exponential function, which is produced by the variation of specific heat ratio during the reaction process, physically. A new overall one-step detonation model with variable specific ratio and gas constant is proposed to improve the property of Arrhenius law. Two dimensional numerical simulations with this new model are conducted, and the detonation cell sizes are in agreement with experimental results quantitatively.
