摘要
应用Strawn&Kline的准同时粘性/无粘流匹配模型,于动量积分方程中加入了曲率和雷诺正应力两个二阶修正项,计算了二维不可压湍流附面层分离流动。文中首先分析推导了新的曲率修正公式,给出了两个算例。比较了修正项对计算结果的影响,并与实验做了对比。
The two second-order terms of curvature and normal stresses wereadded in the Von Karman integral equation to compute two-dimensional incompressible turbulent boundary-layer separation by using Strawn &. Kline's simultaneous viscous/inviscid interaction model. A new correlation of correcting curvaturewas deduced and analyzed. Two examples were presented. The effect of the curvature and normal stress on the calculation was discussed and the calculation wascompared with the experiment in this paper.
