摘要: 用积分方程方法求解 Prandtl- Glauert算子表示的全位势方程 ,并计算了翼 -身组合体跨音速绕流。用 Murman- Cole差分格式计算空间场源强度 ,以捕捉激波。计算结果与相应的实验结果符合良好

Abstract: An integral equation method for solving the full potential equation which is described by Prandtl Glauert operator is developed for wing body combinations in transonic flows. In order to capture the shock wave, Murman Cole type of finite difference scheme is used to calculate spatial source distribution. The numerical results are in good agreement with the results of experiment.
