In this study, we choose 5 horizontal-axis wind turbine (HAWT) blade output has been designed by the blade, and the blade aerodynamics are also simulated to investigate flow structures and aerodynamic characteristics. The design conditions of the turbine blade in order to display the rated wind speed, design tip speed ratio and design angle of attack that have been set to 10-30 m/s, 0,5 and 10°, respectively turbine blade. The last selection is NACA 4412 that has the best performance between 5 selected airfoil. The simulation results are compared with the improved BEM theory at rated wind speed of 10-30 m/s and show that the CFD is a good method on aerodynamic investigation of a HAWT blade.in this study we use two soft wares(fluent &Q-Blade) for our computations.
