摘要：

A comprehensive introduction on mathematical models of gas detonation modeling is given in this paper. Different thermodynamics models and chemical reaction models are described. A code has been developed to simulate gas detonations in two-dimensional complex geometries, and it is used to simulate shock-wave propagation in a detonation arrestor. Operator split method is used to solve the conservation equations. The flux corrected transport (FCT) scheme is used to solve the Euler equations of gas dynamics and the CHEMKIN code is used to calculate the thermodynamics properties and chemical reaction rate. Comparison is made between the simulation results with experimental results of a former research, and the simulated shockwave propagation has good agreement with the experimental Schlieren photographs in general.
