Abstract

Blade tip winglets can effectively improve the aerodynamic performance of wind turbine wind wheels. However, most of the existing tip winglets are realized by blade extension technology, which changes the diameter of the wind turbine, so it difficult to analyze the effect of tip winglets on the aerodynamic efficiency of the wind turbine. To address this problem, based on numerical simulation method, the aerodynamic performance and flow field characteristics of the wind turbine with different mounting positions of the blade tip winglets are characterized on the basis of the NREL 1.5 MW wind turbine. Through numerical simulation analysis, it is found that the winglets can cut down the flow separation phenomenon near the blade tip, weaken the tip vortex, and increase the pressure difference between the pressure surface and suction surface of the wind turbine, thus improving the aerodynamic efficiency of the wind turbine. Meanwhile, it is found that the winglets closer to the blade tip had better improvement on the aerodynamic performance of the wind turbine. At rated wind speed, the installation of winglets at the blade tip can increase the power by 2.05%.
