摘要
为耦合使用冲击爆轰计算工具箱SD_Toolbox和化学动力学开源代码Cantera计算混合气体爆轰问题,开展了气体ZND爆轰结构参数计算与分析,同时给出了SD_Toolbox和Cantera应用于惰性气体阻尼效应研究的一个应用实例。在介绍了使用SD_Toolbox和Cantera进行气体ZND爆轰计算的基本方法后,以H_2/空气混合物CJ爆轰和H_2/空气混合物过爆轰为例,计算了其ZND的两个特征尺寸,并得到了爆轰产物压力、密度及主要产物成分百分比的计算结果,经与文献结果对比证明了本文结果的正确性。最后,将SD_Toolbox和Cantera耦合计算应用到一个实例,即进行惰性气体对爆轰反应进程阻尼效应的研究,并验证了结果的正确性。
For the purpose of studying the detonation problems of mixed gases further, by employing the professional program for shock and detonation named SD_Toolbox and the chemical kinetics open source code named Cantera, investigation about calculating the gaseous ZND model detonation parameters has been carried out. Meanwhile, examples of damping effect of the inert gas on the gaseous mixture detonation is provided, which is researched by using SD_Toolbox and Cantera. After an introduction of the calculating method of the ZND model detonation parameters, two cases of mixture H_2/air in CJ detonation and overdriven detonation has been calculated and two length scales as the induction length and the energy pulse are obtained, as well as the detonation product pressure, density and percentage of main product composition. By comparing with literature, the calculations have been verified. Finally, damping effect of the inert gas Ar on detonation problem of mixture H_2/O_2 and CH_4/O_2 is investigated, and also the results are verified.
