| Abstract | 利用欧拉方程和单步化学反应模型,对斜爆轰波进行了数值模拟,重点研究了斜爆轰波面上多维复杂结构的形成机理,数值结果显示在斜爆轰波面上,存在两种小尺度的激波和火焰耦合结构:第1种结构由一道横波和三角形火焰组成,是斜爆轰波中特有的结构;第2种结构由两道横波和凸起的火焰面组成,类似于正爆轰波面上的胞格结构.数值结果表明这两种结构具有相同的形成机理,而且能够相互转化,它们的形成和发展过程受到来流马赫数和化学反应放热速度等参数的影响. |
| Other Abstract | The oblique detonation waves are simulated numerically to study the fine structures on the detonation surface,with Euler equations and the one step chemical reaction model.Two kinds of complicated structures are observed on the oblique detonation surface.One is composed of the transverse wave and triangle flame,which is special on the oblique detonation surface.The other is similar to the cellular structure on the normal detonation surface,but rarely observed on the detonation surface before.Simulation results demonstrate that they have similar mechanisms and can be converted into each other.Their formation and evolution processes are influenced by the inflow Mach numbers and the activation energy values. |
