| 摘 要： | 采用数值模拟方法研究沈阳航空航天大学高速叶栅风洞试验段流场,由于试验段上下壁板间的垂直高度是随着叶栅攻角的改变而变化的,这就造成了过渡段上下壁收缩曲线的不对称,这其中的气流流场是不均匀的,通过对CFD数值模拟计算结果的比较和分析,最终选择合适的过渡区上下壁面收缩曲线,使得叶栅试验段处得到均匀稳定的流场,达到预期的效果,使得由上下壁面型面曲线不对称而引起的气流不均匀问题得到很大改善。

| Abstract: | This paper introduces the numerical simulation of the flow field of the High-speed Cascade Tunnel test section in Shenyang Aerospace University.The height between the top wall and the bottom wall of test section changes with the change of cascade angle of attack,so the wall curves of transition section between the test section and the contraction section are not symmetrical,and the flow field is not uniform.The applicable contraction curve is selected by analyzing the results of numerical simulation of CFD,... |
