Abstract: The vortex generator can control the flow separation of the boundary layer of the wind turbine and effectively improve
the aerodynamic characteristics of the wind turbine. Based on the method of numerical simulation, this paper studied the influence
of vortex generator on the aerodynamic characteristics of wind turbine blades. The results show that the vortex generator could
effectively improve the aerodynamic characteristics of the blade and restrain the flow separation of the boundary layer on the suction
surface of the blade. At the same time, the effect of adding vortex generators in transition on the pressure coefficients, thrust
coefficients and torque force coefficients was analyzed.
