摘要
通过求解雷诺平均N-S方程组,完成了涡流发生器绕流流场及其气动影响的数值模拟。通过对安装单个涡流发生器的平板绕流进行数值模拟,验证了计算方法的合理性。在多段机翼的后缘襟翼上安装一排涡流发生器,可以提高升阻比,改善气动特性。
In this paper,the flow around vortex generator is simulated by solving the Reynolds-averaged N-S equations.By simulating the flow of single vortex generator on flat plate,the calculation method is verified.The computational results show that vortex generator installed on the trailing edge flaps of multi-element wing can increase lift-drag ratio and improve aerodynamic characteristics.
