对爆轰CJ模型和ZND模型合理性的讨论
Comments on the Unjustification of CJ and ZND Model in Detonation
【摘要】 CJ模型和ZND模型未充分考虑爆轰过程中由于热量瞬时释放所带来的本质变化 ,它们所确定的爆轰终点状态是所有可能状态中熵值最低的 ,实现的概率极小。终点状态应该由热力学确定 ,ZND模型达不到热力学确定的平衡终态。爆轰模型应该同时符合流体力学定律和热力学定律
【Abstract】 The essential change caused by sudden heat energy release in a detonation process is not fully considered by the CJ and ZND model.In these classical detonation theories,the entropy at the final detonation point is the lowest one among all possible states,and the probability is the lowest .The final detonation point shall be decided by the thermodynamics,which can not be achieved through the ZND model.The fluid mechanics and thermodynamics laws must be satisfied in a goog detonation model.
