| 摘 要： | 为研究含能材料在激光作用下的点火特性,从基本守恒方程组出发,基于详细化学反应动力学模型,建立了含能材料激光点火的气相模型.利用所建立的模型对RDX在激光辐照下的点火过程进行了数值模拟,得到了点火过程中的瞬时温度分布和组分分布,对点火特性进行了分析.计算得到的不同激光功率密度下的RDX点火延迟时间与文献结果一致.

| Abstract: | In order to investigate ignition characteristic of energetic materials radiated by laser,a gas-phase reaction model was established using detailed chemical kinetics.In the model,45 species and 232 reaction steps was used to describe gas phase mechanism.Then the model was used for modeling the process of laser-induced ignition of RDX.Temperature distributions in both condensed and gas phase were obtained to analyse the process of ignition of RDX.Mole Fractions of main species were presented to show the chemi... |
