One-dimensional overdriven detonation initiation is investigated numerically within a finite rate detailed chemical reaction model. 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。
And then the re-intension of a detonation wave takes place downstream of the acoustic absorbing walled section, accompanying with the onset of an overdriven detonation at some distance away from the exit of the acoustic absorbing walled section. 该非稳定爆轰波传出声学吸收段后再次加强,并在距声学吸收段出口端一定距离处突然发展成超驱动爆轰。
