| Abstract: | he hazards,the mechanism of Deflagration to Detonation Transition(DDT) and the numerical simulation of DDT for a high energy solid propellant are reviewed with a view of grain safety consideration of solid rocket motor.The key processes in DDT such as dynamic compaction,compressive combustion,hot spot formation,constitutive models and closure are specially discussed in this paper.The subjects for future research are proposed. |
