| 摘 要： | 为了研究波形壁湍流及由波形壁引起的扰动场,本文将N-S方程的联立解法应用于湍流。扰动场是从时间平均的湍流场中直接分解出来的。由此计算的类Stokes层仅局限于壁面附近的薄层内,它的特征可以通过对扰动场的分析加以解释。

| Abstract: | To study the turbulent flow in a channel with wavy wall and its disturbance field, the simultaneous iteration approach for N-S equations is applied to the turbulent flow. The disturbances are decomposed from time-averaged magnitudes directly. The Stokes - like layer is confined to a thin layer near the surface and its characteristic can be explained by the analysis of disturbance. |
