Taking H-type vertical-axis wind turbine as the main research object,we explore the selection of lift-type blade airfoils,and analyze the influence of relative thickness,curvature and type of airfoils on the utilization of wind energy of vertical-axis wind turbine based on the simulation results of nine airfoils of three types in the operating conditions of the wind turbine.The influence of each factor on aerodynamic performance is analyzed through numerical calculations,and the change of vortex field around each blade of the wind turbine is analyzed,and the reasons for the change of aerodynamic loads are discussed.The results show that the relative thickness of the airfoil can be increased within a certain range to improve the performance of the wind turbine.The increase of the curvature of the airfoil will cause a decrease in the performance of the wind turbine.It is difficult to obtain the ideal performance of horizontal axis wind turbine airfoils on vertical axis wind turbines,and symmetrical airfoils can be prior-itized in the selection of airfoils.
