| 摘 要： | 针对激波破坏超声速气膜冷却的机理,本文提出了一种壁面开孔的结构,数值研究结果表明：一方面,壁面开孔的结构能使激波作用的区域壁面附近的压力分布较均匀,从而使近壁区的马赫数分布比不开孔的壁面要高,有利于超声速气膜冷却。同时在激波的作用下,冷却气体可以通过开孔壁面的孔进入槽道内,而在槽内的下游再从孔里流出,保护下游的壁面,这...

| Abstract: | A porous surface structure which reduces the effect of the shock wave on the film cooling was developed by the understanding of the mechanism by which the shock wave affects the supersonic film cooling,the numerical results indicated that the pressure is more uniform and the Ma number is larger than those of the wall without porous surface,which is benefit to the film cooling;with the effect of shock wave,the cooling stream can flow into the cavity upstream of the porous surface,and flow out downstream of t... |
