摘　　要：该文采用数值模拟的方法,分别使用S-A、标准k-ε、RNG k-ε和SST k-ω四种湍流模式,对NREL PHASE VI风力机的空气动力学性能进行研究。计算涉及六种速度的来流工况,将轴扭矩、叶片截面压力分布和表面极限流线等计算结果与实验结果进行了对比,并分析了不同湍流模式对计算结果的影响。Presented in this paper is an evaluation of turbulence models for aerodynamic prediction of the NREL PHASE VI Rotor. A three-dimensional incompressible Reynolds Averaged Navier-Stokes solver is used for all cases. Computations made under same operational conditions and computational parameters are carried out with four different turbulence models to draw conclusions on the adequacy of models for the wind rotor flows. Calculations of the rotor are made for a range of axial wind conditions. Comparisons of computed results with experimental data in the form of shaft torque, pressure distributions and limiting streamlines on suction surface are shown. And it is found that the best overall agreement with experimental data is obtained with the SST k - ω model.
