硝基甲烷激波转爆轰的分子模拟
Molecular Simulations of Shock to Detonation Transition in Nitromethane
摘要：
在以前的工作中描述的模型的扩展Maillet，Soulard和Stoltz基于耗散粒子动力学的提出和应用到液体硝基甲烷。硝基甲烷在持续冲击波条件下反应的大规模非平衡模拟，可以更好地理解在均质炸药的冲击到爆轰的转变。此外，反应波的传播似乎是不连续的，因为被冲击的材料中的点火点可以被从化学反应开始发射的压缩波激活。
英文摘要：
An extension of the model described in a previous work of Maillet, Soulard and Stoltz based on a Dissipative Particule Dynamics is presented and applied to liquid nitromethane. Large scale non-equilibrium simulations of reacting nitromethane under sustained shock conditions allow a better understanding of the shock-to-detonation transition in homogeneous explosives. Moreover, the propagation of the reactive wave appears discontinuous since ignition points in the shocked material can be activated by the compressive waves emitted from the onset of chemical reactions.
