本文提出了一些缝隙大小对高超音速分离流影响的实验结果。结果表明,缝隙大小明显地影响分离区范围,缝隙加宽使分离区缩小;缝隙存在也改变了分离状态下控制翼面的压力分布与传热分布。
In this paper, some experimental results on the influence of gap size on hypersonic separation flow are proposed. The results show that the size of the gap significantly affects the range of the separation zone, and the widening of the slit narrows the separation zone. The existence of the gap also changes the pressure distribution and heat transfer distribution of the control airfoil under the separated condition.
