| 摘 要： | 本文用有粘/无粘干扰迭代的概念计算了跨音速任意翼型的绕流问题。位流的速位方程用AF2格式求解,而边界层微分方程用C-S盒式法求解,逆算法的引用可以克服边界层方程在分离点处的奇性问题,对分离区湍流代数模型的修正可以得到与实验更吻合的结果。计算结果表明有粘/无粘干扰迭代概念在小分离泡的情况下也是适用的。

| Abstract: | Transonic flows of airfoils are analyzed with the viscous/inviscid interaction concepts in this paper A full potential airfoil code is coupled with direct or inverse differential boundary layer method.The AF2 schemes and C-S box method are used in potential flow and boundary layer calculation respectively.The modification to the turbulence model in separation regions makes the computational results more agreeable to that of experiments,which indicates that the visccus/inviseid interaction concepts can be applied to the separated flows. |
