摘要
Abstract
The deflagration-to-detonation transition (DDT) model of the granular HMX was established based on the two-phase detonation model. The equation of state of the gas products was described by the calculated results of the CHEQ-like program which was based on the statistical mechanical theory. The DDT process of the granular HMX beds with an average grain size of 125/~m was numerical simu- lated by the CE/SE method. The effects of the loading density on the DDT was studied and compared with the experimental results. Numerical results indicate that the run distance to detonation has a U- shaped relation with the loading density.关键词
