| 摘 要： | 研究了甲烷-空气混合物爆轰波在二维突扩通道中传播的各种复杂行为。结果表明：爆轰波在进入突扩通道的初始阶段有局部向爆燃转变的现象；爆炸波在壁面发生马赫反射形成的高温高压区域将直接驱动自持爆轰波的重新形成。

| Abstract: | The change of the detonation intensity and the behavior of the wave are studied by a numerical simulation. It is shown that the detonation wave is weakened to deflagration partly in the initial stage of propagating into the large section channels, and the detonation is re-ignited by the high pressure and high temperature zone generated by Mach reflection created by the interaction of the shock wave and the well. |
