摘要：
The wind lens is a new external auxiliary device applied to the vertical axis wind turbine. In order to explore the influence of the wind lens structure on the aerodynamic performance of the vertical axis wind turbine，its configuration was optimized by numerical simulation and Bezier curve. The results show that the wind lens has good wind collecting performance，which is helpful to improve the aerodynamic performance of the vertical axis wind turbine. Among the structural parameters of the wind lens，the half-open Angle of the diffuser has a great influence on the aerodynamic performance of the wind turbine，followed by the flange. The optimized configuration of wind lens can further improve the wind energy utilization coefficient and torque coefficient of the vertical axis wind turbine，and the wind energy utilization coefficient can be up to 8.60 times of the reference vertical axis wind turbine. The vertical axis wind turbine can still maintain high operating efficiency under the condition of a larger sharp-speed ratio，and further improve its effective operating range. © 2023 Science Press.
