| 摘 要： | 解决大攻角洞壁干扰修正的壁压法,是利用一定数量固定位置和形状的线源和线涡来模拟风洞内模型的堵塞效应和升力效应。矩形风洞实验段边界对绕模型流动的影响,可用两个方向有限层的镜像线源和线涡来代替,并利用在风洞上下壁和侧壁上测压点处测量所得

| Abstract: | The influence coefficients at the roof and floor, sidewall and centerline of wind tunnel due to the line sources or vortices have been computed using the modified vortex-lattice method, for the purpose of utilizing the wall pressure method suggested by Hackett to the wind tunnel with non-rectangular cross section. The calculation and comparision of the test data on the same model,using the influence coefficients obtained from the image method separately,are also carried out. Finally, the effects of the fillet size over corrected results obtained from different methods are discussed. |
