摘　　要：分别以固壁条件和洞壁附近的压力分布模拟各类实壁和透气壁试验段的洞壁边界条件，利用Euler方程和N－S方程数值求解模型在风洞中的绕流场，得出洞壁干扰对跨声速模型统流和气动力的影响。初步的研究结果表明，该方法能较有效地模拟模型在跨声速风洞中的绕流场，经洞壁干扰修正后的GBM－04A模型在0．6m风洞中的试验结果与无干扰参考结果吻合较好。The paper discusses our current effort to develop the method for the calculation of transonic wind tunnel wall interference.The wall effects on the tunnel flow fields over the model and its aerodynamic forces and moments are determined by using the solid wall conditions or measured pressure distributions near walls as the boundary conditions of test section and numerically calculating the tunnel flow field over the model based on Euler and N-S equations.Preliminary researches show that the method can effectively simulate the transonic tunnel flow over the model, and corrected test results in 0.6m wind tunnel are in quite good agreement with the free-interference reference data.
