Numerical simulation on aerodynamic performance of an airfoil for wind turbine

2D physical and mathematical model was built to simulate the flow around NACA63-215 airfoil,then the steady compressible Reynolds-Averaged Navier-Stokes equations were solved numerically and both Spalart-Allmaras and Baldwin-Lomax turbulence model were applied to solve the turbulent viscosity using the CFD commercial software called NUMECA.The coefficients of lift and drag as well as the pressure distribution were concluded with the change of angle of flow attack for airfoil NACA63-215.The comparison between computed results and experimental data showed that predicting results of Spalart-Allmaras turbulence model were closer to the experimental results and can be more effective in predicting aerodynamic performance of airfoil after stalling.
