ABSTRACT

To optimize the aerodynamic characteristics of a certain S-shaped airfoil horizontal-axis wind turbine independent intellectual property rights of a certain research group, this paper performs blade shape parameter optimization based on Wilson and Glauert design theory. This study focuses on the aerodynamic performance of both the optimized blade design and the research group's baseline blade. Utilizing the flow field analysis module of ANSYS, we investigated the rotor's torque, power, and power coefficient at six fixed wind speeds. Furthermore, the pressure distribution, pressure coefficient, and velocity streamlines around the airfoil were analyzed at various angles of attack. We can see that the new wind turbines have a higher torque by 10.70% than the original wind turbines’ torque, the new wind turbines also have more power than the original wind turbines by 4.2%. At the tip speed ratio close to 5, the new wind turbine and the old wind turbine both have the largest power coefficient. When the wind speed is 8m/s and 10m/s, the newly built wind turbine wind energy coefficient is 3.9% and 2.24% greater than the old wind turbine. The curvature of the airfoil is increased, and the maximum value of the lift coefficient is also increased, so the tangential induced velocity is decreased, the turbulent diffusion on the suction side of the blade is decreased, and the energy loss of the pulsation of the airflow is reduced. Through the optimization of the new blade, it is possible to delay the separation of the boundary layer, to improve the aerodynamic performance parameters such as power and torque, and can be applied to the optimization design of horizontal-axis wind turbine blades.
