Abstract: The present paper report the numerical solution of horizontal axis wind turbines (HAWTs) of the aerodynamics by using computational fluid dynamics, CFD with three turbulence model, and compare these turbulence model results with experimental data to validate and determine which one is more reliable for numerical solution. Computational domain was divided in two zones; rotating and stationary .The numerical solution was carried out in the rotation zone, by solving conservation equations in a rotating reference frame. The blades have fixed 12° pitch angle and the computational results for different turbulent models such as standard k-å, RNG k-å &Spalart- Allmaras has been reported and compare with the experimental data of The National Renewable Energy Laboratory (NREL), for two wind speeds. It seems that the one-equation Spalart-Allmaras model is the suitable for turbulence closure, in low wind speed, and RNG k-å model is more reliable for higher wind speed.
