摘　　要：为研究混合气体爆轰问题,通过利用冲击爆轰专业计算工具箱SD_Toolbox和开源的化学反应动力学计算代码Cantera研究了气体C-J爆轰参数计算方法与规律。结果表明:将SD_Toolbox和Cantera耦合可以进行混合气体爆轰问题的C-J爆轰参数计算;以H_2/O_2、CH4/O_2和C_2H_2/O_2三种不同的混合气体组分为例,在化学反应比初始条件下,分别计算了其C-J爆轰参数;通过与文献中结果的比较,验证了计算的准确性。可见,基于SD_Toolbox和Cantera可以进行气体C-J爆轰参数规律分析,包括初始温度、初始压力和爆炸气体浓度对爆轰产物压力、密度、温度和爆轰波速的影响规律等。In order to study the gaseous mixture detonation problems,the professional computing program code for shock and detonation named SD_Toolbox and the open source code for chemical kinetics named Cantera were used to investigate the gaseous C-J detonation parameters calculations and regularity analysis.The results show that the gaseous C-J detonation parameters of mixture detonation problems can be calculated by coupling SD_Toolbox and Cantera;taking the stoichiometric gaseous mixture H 2/O 2,CH 4/O 2 and C 2H 2/O 2 as examples,the C-J detonation parameters has been obtained by using SD_Toolbox and Cantera respectively;comparing with results of refrences,the accuracy was verified.It is concluded that on the basis of SD_Toolbox and Cantera the regularity analysis could be done,such as effects of initial pressure on detonation product pressure,density,temperature and the detonation velocity,as well as effects of initial temperature and explosion gas concentration on these detonation parameters above.
