Re-initiation was induced by the leading shock reflection on the right wall in the vertical branch. 诱导激波在垂直支管右壁面反射,诱导二次起爆。
Numerical analysis of re-initiation phenomenon induced by shock reflection 激波反射诱导二次起爆的数值分析
High temperature and pressure behind the reflected shock induce the generation of hot spots and local explosion. Then, the re-initiation of gaseous detonation occurs. 反射激波在诱导激波压缩后未燃气体中传播,使得波后压力和温度进一步升高,诱导热点产生和局部爆炸,导致二次起爆。
The re-initiation phenomenon of gaseous detonation in a heart-shape tube was numerically studied. 针对心形管内气相爆轰二次起爆过程进行了数值研究。
