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
Wall pressure method, which is used to solve the wall interference correction at large attack angles, is to simulate the clogging effect and lift effect of the model in the wind tunnel by using a certain number of fixed position and shape line sources and line vortices. The influence of the boundary of the rectangular wind tunnel on the flow around the model can be replaced by the mirror source and the line vortex of the finite layers in both directions. The measured values at the pressure measuring points on the upper and lower walls of the wind tunnel and the sidewall
