| 中文摘要: |
| 本文实验研究了氢/氧/氩气体爆轰波在矩形管中900尖角绕射时的传播特性,利用烟迹技术记录了实验现象,运用爆轰波波阵面结构理论和激波绕射及反射理论对实验结果作了分析。结果表明平面气体爆轰波在900尖角绕射时由于横波失去碰撞以及稀疏波作用,稳定三波结构在绕射区发生变化,在反射激波作用下形成热点产生子爆炸,重新在垂直分支管中形成稳定爆轰波。 |
| 英文摘要: |
| The diffraction and reflection of detonation waves in hydrogen-oxygen-argon mixt ures through a tube with a sharp-angled 900 bend were studied in the article exp erimentally. Cells of gaseous detonation waves were recorded using smoke soot me thod. Results indicate that the transverse waves’ collision disappearing result s in cells’ deformity when detonation waves transmit through a sharp-angled 900 degree. In the branch tube, the reflection of leading shock waves induces re-ig nition and gaseous detonation stable cellular structure forms in a certain dista nce. |
