| 摘 要： | 将结合SSTk-ω湍流模型的γ-Reθt转捩模型与二维雷诺平均NS（RANS）方程数值求解相耦合,发展了考虑转捩影响的翼型气动特性计算方法。得到的计算结果与没有考虑转捩影响的计算结果的比较表明,与实验更加吻合,计算精度得到了明显提高。

| Abstract: | An improved method for the prediction of airfoils′ aerodynamic characteristics is developed in this paper.The γ-■θt transition model based on SST k-ω turbulence model is implanted in our two-dimensional RANS（Reynolds Averaged Navier-Stokes Equations） Solver to enhance the accuracy of computation.Compared with the method without considering boundary layer transition,the computational results show that our method is more consistent with the experimental data,and the accuracy has been improved significantly. |
