摘要

通过求解雷诺平均Navier-Stokes方程考察Spalart-Allmaras、Wilcox'sk-w和Menter'sSST三种湍流模型在跨声速流动中的计算精度。结果表明:Menter'sSST模型预测的力和力矩最接近实验数据;Spalart-Allmaras模型的压力分布和激波位置与Menter'sSST模型的一致,Wilcox'sk-w模型的激波位置相对偏后,且预测的升力和摩擦阻力偏大。

Abstract

The computation accuracy of three different turbulence models including Spalart-Allmaras model, Wilcox's k-w model and Menter's SST model in transonic flow was investigated by solving Reynolds averaged Navier-Stokes equations. The results show that the computed force and moment using SST model has the highest accuracy compared with the experiment. The predicted distribution of pressure and position of the shock wave using Spalart-Allmaras model agrees very well with those from Menter's SST model. The predicted position of the shock wave using Wilcox's k-w model is slightly backward compared with that of SST model.

Key words： computation accuracy; Navier Stokes equation; transonic flow; turbulence model
