| Abstract: | In this paper the Deflagration to Detonation Transition (DDT) process of combustible gases and Mach Reflection of a detonation wave on a wedge have been numerically simulated with a simplfied two step model (ZND) of chemical reaction and the improved method of space time conservation element and solution element (CE/SE).The computational results were primarily analyzed.The numerical results were compared with experimental results.Compared results are satisfactory.This is the first time to apply the CE/SE method to the chemical reaction flow,especially to the simulation of the DDT process of combustible gases and the Mach reflection of detonation waves. |
