The aerodynamic performance of wind turbine airfoils was an important foundation for the aerodynamic design and the performance analysis of the wind turbine. In this paper, fluent aerodynamics performance of a wind turbine airfoil S414 is simulated based on CFD. Its pressure coefficient with different angles of attack was obtained. The numerical results are compared with the experimental data, which proves the simulation data of Spalart-Allmaras equation is fit for airfoil S414. The theoretical foundation is established for three-dimensional flow simulation of airfoil in the future. Besides, adopting Spalart-Allmaras turbulence models can improve the predicting results for aerodynamic performance. The proposed method provides an effective way to predict the aerodynamic characteristics of wind turbine. This study provides quick and valid numerical simulation methods for wind turbine airfoil aerodynamic designing and possesses higher utility value in engineering.
