Abstract—Design of wind turbine blades strictly depends on high precision, reliable and robust numerical predictions of its performance in all of operation conditions. This paper aims to simulate the flow around horizontal wind turbine blade with Computational Flow Dynamics (CFD) using a validated 3D Navier–Stokes flow solver. The main objectives of this study are investigating of different turbulence models and aerodynamic performance of wind turbine blades. The NREL Phase VI rotor used for CFD simulations and testing. Three different turbulence models included of Spalart- Allmaras, k-epsilon (Launder Sharma) and k-ω SST tested and the best model for prediction of wind turbine performance is provided. Since Mach number is less than 0.3, the flow around wind turbine blade is incompressible and precondition used. For all cases the structure grid used for Fluid reticulation grid. For results more accuracy, use of preconditioning is necessary. Outputs of flow solver are t power and pressure coefficients for each section. At the final the k-epsilon with preconditioning code is selected the best model for simulation of flow around wind turbine blades.
