摘　　要：本文通过Coles速度分布公式中常系数的综合修正,将旋转与曲率的影响引入湍流结构,并与带旋转和曲率项的动量积分方程相联立,使用简单迭代的计算方法,求解了带旋转和曲率的二维不可压湍流边界层.In this paper the effects of rotation and curvature on the turbulent structure are taken into account by introducing Coles velocity profiles with modified constants. By means of the momentum integral equation combined with the profiles, a two-dimensional incompressible turbulent boundary-layer with rotation and curvature is numericaely sollved by a simple iteration method.
