The eddy viscosity in the buffer zones of the turbulent boundary layers was limited to investigate its effects on the points of incipient separation for flows over wind turbine airfoils. Thek – ? SST turbulence model was used as the base model within the framework of a finite volume CFD scheme. Flows over two different wind turbine airfoils were computed and compared with experimental results. Much improvements in the lift and drag coefficients in the stall regions were observed when compared with the results of the original turbulence model.
