摘要
利用化学动力学及流体力学原理 ,建立了沼气爆炸状态参数计算模型 ,用于计算在巷道内沼气爆燃向爆轰转变过程 (DDT)中 ,系统温度和连锁反应自由基的变化情况。研究表明 ,温度和自由基对沼气爆燃向爆轰转变过程起综合性的促进作用 ,而自由基团 [OH]和CO对这一转变过程有决定性影响。
Based on principle of chemical kinetics and aerodynamics,a simplified mathematical model for methane explosion is established.Change of system temperature and midterm factors are studied in the transition process from deflagration to detonation.The results show that temperature and midterm radicals play a comprehensive boosting role in this process,and radicals such an [OH] and CO are very inportant to DDT process.
