利用有限速率的基元反应模型对一维过驱动爆轰波的形成过程进行数值模拟．研究表明，在上游高温、高压、高速来流作用下首先会形成一道强激波，其波面方存在诱导区和放热区，然后诱导区和放热区界面会在来流扰动的作用下发生失稳，经过复杂的波系运动过程形成过驱动爆轰波．通过对不同初始条件下界面失稳过程的模拟和分析，研究了混合气体的组元、温度，来流的压力、温度、速度对过驱动爆轰波形成的影响． |

One-dimensional overdriven detonation initiation is investigated numerically within a finite rate detailed chemical reaction model. Numerical results exhibit that due to upstream inflow at high temperature, pressure and velocity, a leading shock followed by induction and heat-release zones appears. Because of inflow disturbances, the interface between induction and heat-release zones becomes unstable and overdriven detonation waves are generated. With simulation of unstable interfaces with different gas species, temperatures, inflow pressures and velocities, overdriven detonation initiation process is analyzed and illustrated. |
