中文摘要：

燃气轮机气膜冷却流动中的复杂涡系使得其湍流黏性系数体现出很强的各向异性。本文采用作者提出的代数各向异性湍流黏性系数修正方法（AAEV方法）,对不同孔型气膜冷却进行了研究。文中结合平板圆孔、扇形孔气膜冷却实验结果,将传统的湍流模型与修正后的湍流模型获得的模拟结果与实验值进行了比较,得到修正后的结果与实验有较好的吻合度。修正后的湍流模型对不同的孔型有很好的适用性,同时揭示了两种孔不同的三维特性。

英文摘要：

The complex vortices in film cooling flow make the turbulent eddy viscosity fully anisotropic.This paper applies the algebraic anisotropic eddy viscosity model（AAEV） developed by the authors to investigate the performance of the new model on different geometry film cooling flows. Comparison among the anisotropic model,the traditional turbulence model and the experimental data is taken.The anisotropic turbulence model gives a better result and has a good applicability for different hole geometries.Furthermore,this study reveals the different flow characteristics of the two geometries.
