摘要：
In order to improve the aerodynamic performance of wind turbine, a double-wings blade based on the blade of NREL Phase VI horizontal axis wind turbine is studied. By the method of computational fluid dynamics, the comparison of torque and bending moment between NREL Phase VI wind turbine scaling blade and double-wings blade under the same conditions is made to analyze the influence of rotor solidity. The fact that the aerodynamic performance of double-wings blade is better than that of the original NREL Phase VI wind turbine blade is not caused by the increase in solidity. Furthermore, the numerical simulation of double-wings blades with different chord length ratios, vertical distances and horizontal distances is conducted and the influence of horizontal distance on the aerodynamic performance of wind turbine is analyzed emphatically by the velocity streamlines at different cross sections along the blade spanwise direction of double-wings wind turbine. Finally, the variation trend of aerodynamic performance with geometric parameters of double-wings blade is summarized. The results show that at the wind speeds of 15 m/s to 25 m/s, the double-wings blade with a larger chord length ratio, a larger vertical distance or a smaller horizontal distance can obtain a larger torque, but the bending moment will also increase accordingly. © 2023 Editorial Office of Chinese Journal of Mechanical Engineering.
