Abstract
The steady numerical simulation was investigated and the aerodynamics performance of wind turbine airfoils DU-93-W-210 and S809 was analyzed using ANSYS Fluent based on wind tunnel testing data. There is considerable inconsistence of the drag coefficients between the simulations and the experimentally measured data because the simulations are based on a turbulence model for the entire computational domain, particularly at small angles of attack where a considerable portion of the flow upon the suction side of the airfoil is laminar flow. The CFD model was re-addressed by defining turning points of laminar and turbulence flows on both pressure and suction sides of the airfoil and the prediction accuracy of the drag coefficients was improved at small angles of attack.
