摘要：

In order to improve the aerodynamic performance of VAWT, for a small double-blade H-type vertical axis wind turbine, three kinds of arrangement position schemes of vortex generator on the blade surface were proposed. The simulation model was established for the wind turbine, and the grid independence was verified. By using ANYSY FLUENT software, three-dimensional hydrodynamic simulations of conventional airfoils were performed. The results show that the blade torque coefficient can be improved by adding vortex generators on the inner surface of the upwind zone and the outer surface of the downwind zone, but the analysis of the flow field shows that the flow field in the downwind zone is disordered, and the lifting effect of vortex generator installed on the outer surface of the blade in the downwind area becomes worse. Among the three schemes, when the vortex generator is installed on the inner and outer surface of the blade, the wind energy utilization ratio CP of the vertical axis wind turbine is the best, and the wind energy utilization ratio is increased by 6.4% compared with CP of the original wind turbines. © 2020, Central South University Press.
