Studies on the wind turbine have been attempted because not only its mechanical performance but also acoustic noise becomes important issue. Regarding numerical modeling and simulation, researchers must precisely evaluate aerodynamic phenomena on limited memory and CPU resource. This paper presents several preliminary results from simulation of the NREL phase VI wind turbine, using a 3D-CFD-RANS turbulence model (Spalart-Allmaras and SST k-ω), and shows the comparisons between CFD results of 2 turbulence models and experimental results about pressure coefficient on a blade in the case the wind speed is 25m/s. These comparisons are made in the blade with 0° yaw angle, 3° tip pitch angle and 72 rpm (test sequence S).
