摘　　要：为了研究不同湍流模型对风力机翼型气动性能模拟的影响,以风力机专用翼型DU97-W-300为研究对象,使用网格划分软件GAMBIT对翼型流场区域进行划分网格,采用FLUENT16.2对翼型进行气动性能分析,比较全湍流S-A模型及带转捩修正的Transition SST模型的模拟结果。研究结果表明,S-A模型计算的升力系数更接近实验值,T-SST模型在小攻角时计算的阻力系数与实验值基本一致,大攻角时有一定误差,但趋势都与试验结果相同。研究结果对风力机翼型的气动性能分析具有一定的参考价值和指导意义。In order to study the influence of different turbulence models to simulate the aerodynamic performance of wind turbine airfoil, with the wind turbine airfoil DU97-W-300 as the research object, this paper classified the airfoil flow areas by using grid mesh software GAMBIT, analyzed the aerodynamic performance of airfoil by using FLUENT16.2, compared the simulation results of fully turbulent S-A model with the simulation results of modified Transition SST model. The research results show that the lift coefficient calculated by S-A model is closer to the experimental value. The resistance coefficient calculated by T-SST model is basically the same with the experimental value at small attack angle. There is a certain error when the attack angle is large, but the trend is all the same with the experimental results. The results have a certain reference value and guiding significance for the aerodynamic performance analysis of the wind turbine airfoil.
