| 摘 要： | 基于两种燃料体系下的DF详细化学反应动力学模型,利用敏感性分析的方法,分别提出了相应的简化反应机理.简化过程中发现,仅考虑DF“冷反应”泵浦过程,忽略掉高振动激发态,忽略掉D2和DF分子的离解复合反应对整个系统影响不大.DF分子之间以及DF与D、D2、HF之间的能量转移反应具有较高的敏感性.简化机理在有效概括DF化学反...

| Abstract: | Based on the detailed DF chemical kinetic models of two different fuel systems,the relevant simplified chemical kinetic mechanisms were presented with the method of sensitivity analysis.It is found that considering the DF cold reaction pumping reactions,ignoring DF higher excited vibrational states and omitting the recombination-dissociation reactions have little effect on the total system.The energy transfer reactions in DF and DF deactivations by D,D2 and HF exhibits strong sensitivity to the chemical kin... |
