边界层流动的非平行稳定性研究

Studies of nonparallel stability of boundary layer

摘要: 采用极为有效的抛物化稳定性方程（PSE）方法研究边界层的非平行稳定性。并利用抛物线坐标变换、有限远延拓外边界条件、及流向和法向全差分的数值方法，对不同频率的二维Tollmien-Schlichting波的非平行稳定性进行了计算和分析。计算结果与Orr-Sommerfeld方程(OSE)的解以及谱配置方法的PSE结果作了详细的比较，得到了满意的结果。

Abstract: In this article the nonparallel stability of the boundary layer is investigated effectively by using the parabolized stability equations (PSE). With the coordinate transformation, the finitely expanded out-boundary condition,and the finite difference tech
