新爆轰模型及其实验验证

从理论、实验和应用三方面论证了作者提出的LADM爆轰模型（Least Action Detonation Model,LADM）.经典爆轰理论CJ模型和ZND模型（简称CJ-ZND模型）是忽略输运效应的一维层流模型.LADM模型用熵原理确定爆轰过程终点,用Hamilton原理确定从炸药到终点的真实爆轰过程,除化学反应外还考虑了输运效应和爆轰产物粒子的复杂运动.X光照片显示,爆轰波反应区后存在一个静止区域,与LADM模型的理论分析结果相符.LADM模型可以描述乳化炸药的压力分布.

A new detonation model and its examination by experiments

The LADM model（Least Action Detonation Model） proposed by Hu et al was analyzed theoretically and examined by experiments.The classical theoretical detonation model,CJ and ZND models（CJ-ZND model in short）,are one-dimensional model neglecting transport effects.In the LADM model,the entropy principle is used to specify the final point of detonation process,and the Hamilton＇s principle is used to find the real path from the explosive to the final point,in which transport effects and complex movement are taken into account besides chemical reactions.X-ray photographes show that there is a stationary region behind the reaction zone of detonation wave,which coinsides with the LADM model.The pressure profile of emulsion explosive is studied by the LADM model.
