| 摘 要： | 对超音速燃烧室内各种构型的凹槽流场进行了数值模拟,研究了凹槽的后壁面斜角、凹槽长高比及凹槽前后壁面高度比等参数对凹槽流场的影响,计算了各种构型凹槽的阻力、停留时间等。研究结果对定量认识凹槽流场、优化凹槽构型、设计高效率的火焰稳定器具有一定借鉴作用。

| Abstract: | The flow field in the cavities of various configuration of the supersonic combustor was numerically simulated,and the effects of some parameters on flow field in the cavity were investigated,including back-wall oblique angle,length-to-depth ratio,height ratio between front-wall and back-wall,and so on.Resistance and standing time of cavities of various configurational were calculated.The investigation results can be used as a reference for quantitatively describing cavity flow field,optimizing cavity configuration and designing high-efficiency flame stabilizer. |
