Abstract
The flows around DU 97-W-300 and DU 93-W-210 wind turbine airfoils at angle of attack ranging from -180 degree to 180 degree were simulated by the Large Eddy Simulations (LES) method. Compared with the experimental data, the computational results of LES method provide more reliable aerodynamic data than the estimate model and the method based on Reynolds Averaged Navier-Stokes Equations, which shows that the LES method has the superiority in the prediction of aerodynamic data necessary for the structure design and stability analysis of wind turbine blade.
