气相爆轰波平衡胞格稳定性实验研究

本文详细介绍了研究气体爆轰的烟迹法以及采用所提出的方法得到的爆轰波通过柔性材料壁面前后平衡胞格形成、消失和重新恢复的全过程烟迹照片。实验按初压不同分五组进行。从烟迹照片中各时期的胞格尺寸、横波的变化出发,对上述过程中横波强度变化情况及柔性壁面对横波的作用和影响进行了分析,对平衡胞格恢复的条件进行了讨论。

EXPERIMENTAL INVESTIGATIONS ON THE STABILITY OF EQUILIBRIUM CELLULAR IN GASEOUS DETONATION

When (he gaseous detonation wave moves in the shock wave tube. and if we substitute the soft material for the rigrd in a short section of the inside wall, the trans-vers waves will be absorbed by soft wall, the equilibrium cellular structure of gaseous detonation wave will disappear, and then detonation wave will be weaken. When detonation wave departs from the soft wall section, equilibrium cellular will reappear gradually.This paper describes the soot tract method in studies of gaseous detonation. and relates the processes of the equilibrium cellular disappearing and reappearing when detonation wave enters and departs from the section of soft wall. We also discuss the effects of soft wall upon the strength of transverse waves and the conditions of equilibrium cellular reappearance in this paper.
