通过测量洞壁附近的压力分布来模拟透气壁试验段的洞壁边界条件，采用数值求解Euler方程的方法模拟模型在风洞中的绕流场，然后将洞壁边界条件用远场边界条件替换，用同样方法计算出模型在自由流中的绕流场，从而计算出洞壁干扰对模型的绕流场和气动力的影响。针对大迎角模型的洞壁干扰问题的特殊性，采用重叠网格技术，对飞机大迎角标模和SB03模型进行了亚声速大迎角的洞壁干扰计算与修正。
By measuring the pressure distribution near the hole wall to simulate the wall boundary conditions of the ventilation wall test section, the Euler equation is used to simulate the flow field in the wind tunnel. Then the boundary conditions of the hole wall are replaced by the far-field boundary conditions In the same way, the flow around the model in the free flow was calculated, and the influence of the interference of the wall on the flow field and the aerodynamic force of the model was calculated. Aiming at the particularity of the tunnel wall interference problem in the high angle of attack model, the overlapped grid technique was used to calculate and correct the interference of the wall at high angle of attack at high angle of attack.
