| 摘 要： | 本文采用涡格法作为洞壁干扰和支架干扰的修正方法,该方法需要知道包含在高速风洞通气壁边界条件中的透气性参数Q。应用理论计算配合实验的方法确定了FL-21风洞的洞壁特性曲线Q～Ma,洞壁特性参数Q在亚音速时随Ma数增加而增加。文中应用该曲线对一些实验结果进行了洞壁干扰和支架干扰修正,所得结果与国外计算值和国内实验值吻合较好。

| Abstract: | This article presents a method to correct tunnel wall and support interferences based on vortex lattice method. The method needs to know the porosity parameter Q involved in the boundary condition of ventilated wall in the high speed wind tunnel. FL-21 wind tunnel wall characteristic curve Q-Ma is determined by combining computations with experiments. Q increases with Ma in subsonic speeds. According to the curve some test data are corrected for tunnel wall and support interferences. The corrected results agree -well with those attained from theories published abroad and from experiments obtained at home. |
