This research is to study on the optimum design of the wind power generation blade with three different shapes of the wind turbine blade and three air input speeds (7, 10, 15m/s). In order to perform this numerical analysis, velocity, pressure, and temperature distributions of fluid over the flow domain of the turbine blade and also pressure coefficient and ratio of the Lift to Drag force are numerically calculated for the best design shape of blade using commercial CFD code. Finally, the energy-efficient and optimum shape of the wind turbine for power generation are determined with the sequence of case1, case2, and case3.
