Abstract: Based on the improved effect of synthetic jet (SJ) on airfoil aerodynamic characteristics and the configuration characteristics of dual synthesis jets actuator (DSJ), the effects of DSJ actuators arranged at the trailing edge on the aerodynamic efficiency of straight-blade vertical axis wind turbine (SB-VAWT) were studied. By comparing with the experimental results, the accuracy of the numerical simulation results of clean SB-VAWT power coefficient is verified. In order to consider the control effect of the arrangement, the actuation frequency and the momentum coefficient, the Unsteady Reynolds-Averaged Navier-Stokes (URANS) and the SST k-ω turbulence model were used to simulate the SB-VAWT with different types and parameters. The simulation results show that the three arrangement modes of the trailing edge DSJ actuator proposed in this paper can effectively improve the power capacity of VAWT. Among them, Juxtaposition-type is the best. Through periodic “blowing” and “sucking”, the trailing edge vortex is induced to fall off in advance and delay the occurrence of stall. When λ = 2.05, f = 360 Hz, Cμ = 1.975 × 10−2, the power coefficient can be increased by 58.87%.
