本文研究侧壁抽气对二元风洞流场的影响。根据质量守恒关系阐明了侧壁抽气影响风洞势流的双重作用。除了改变侧壁附面层位移厚度从而影响势流的间接作用外,侧壁抽气还有作为源汇分布影响势流流动的直接作用。抽气的后一个作用在过去的研究工作中尚未得到阐明,本文在这方面补充和改善了原有的理论,给出了有侧壁抽气的二元风洞基本方程。在此基础上,进一步提出了最佳抽气的概念。在最佳抽气状态下,侧壁附面层扰动与抽气扰动相互抵消,从而可在二元风洞中实现无侧壁干扰的流动。文中还对实现最佳抽气的可能性进行了探讨。最后,提出了自适应最佳抽气的设想。

The present paper deals with the sidewall suction effect on the flow in two-dimensional wind tunnel. Based on the principle of mass conservation the dual effect of suction is demonstrated. It is found that besides the indirect influence through the variation of boundary layer displacement thickness, the suction also has a direct sink-like effect on the wind tunnel potential flow, which has been neglected in the previous works. On the basis of this analysis, the idea of "optimum suction" is discussed and a defiaition...

This paper presents an investigation on the side wall effect in two -dimensional transonic wind tunnel with sidewall boundary layer suction around the model. The span of the airfoil medel used in the experiments is larger than the width of the test section. Therefore, the model can be shifted laterally and the streamwise pressure distribution for different spanwise section can be obtained. The est results shows that for supercritical flow, the application of sidewall suction will result in an improvement on spanwise uniformity of aerodynamics and a downstream movement of the shock wave.
