摘要

为提升垂直轴风力机气动性能并改善其动态失速特性,将射流襟翼布置于翼型尾缘压力面,并提出5种射流控制策略,采用计算流体力学方法研究不同策略对垂直轴风力机气动性能影响,从而确定最佳控制策略。结果表明：在180°~360°相位角范围内施加射流控制可使风力机风能利用系数在最佳尖速比下提升31.31%,并有效抑制吸力面尾缘涡形成与发展,增大翼面两侧压差;射流越靠近尾缘,垂直轴风力机气动性能提升效果越好。

Abstract

In order to improve the aerodynamic performance of vertical axis wind turbine and its dynamic stall characteristics, the jet flaps were arranged on the pressure surface of the trailing edge of the airfoil, and five jet control strategies were proposed. The effects of different jet control strategies on the aerodynamic performance of vertical axis wind turbine were studied by computational fluid dynamics （CFD）, and the optimal control strategy was determined. The results show that when the jet control is applied in the phase Angle range of 180-360, the wind energy utilization coefficient of the wind turbine can be increased by 31.31% under the optimal tip speed ratio, and the formation and development of trailing edge vortices on the suction surface can be effectively inhibited, and the pressure difference between the two sides of the wing surface can be increased. The closer the jet flow is to the trailing edge, the better the aerodynamic performance improvement effect of the vertical axis wind turbine is.
