| 摘 要： | 基于改进的时 空守恒元解元算法对气相爆轰波数值模拟中3种常用化学反应模型(二步模型，基元反应模型和Sichel的二步模型)进行了考察。对平面爆轰波和具有胞格结构的爆轰波进行了数值模拟，并对数值结果进行了比较和讨论。结果表明3种化学反应模型得到的爆轰参数准确性有所差异，但得到的胞格结构均能和实验结果较好吻合。3种化学反应模型在爆轰波数值模拟中各有优缺点，应视具体问题决定使用哪种化学反应模型。

| Abstract: | Three common chemical reaction models in gaseous detonation numerical simulation have been studied in this work based on an improved space-time conservation element and solution element method.Planar and cellular detonations have been simulated and the numerical results have been compared and discussed.We found that all the cellular patterns simulated by the three chemical reaction models could agree well with the experimental results,though the accuracies of detonation parameters calculated by the three ch... |
