摘要

针对垂直轴风力机复杂气动特性,将吸气孔置于风力机翼型上下表面,提出不同吸气控制策略以改善其气动性能。基于CFD方法,研究不同叶尖速比下吸气策略对风力机风能利用率、叶片切向力系数及流场特性的影响,综合考虑能量消耗与风力机输出功率。结果表明：提出的3种控制策略在低叶尖速比下均能大幅提升整机气动效率。效果最佳的迎、背风区交替吸气策略可显著推迟分离点,延缓翼型动态失速发生,并减少分离涡周期性脱落造成的损失。此外,该策略对动态尾迹效应有良好的控制效果,同时降低整机转矩波动幅值,消除中低叶尖速比下风轮负转矩,从而提高获能效率且延长风力机使用寿命。

Abstract

Aiming at the complex aerodynamic characteristics of vertical axis wind turbine, the air intake holes are placed on the upper and lower surfaces of the wind wing type, and different control strategies for air intake are proposed to improve its aerodynamic performance. Based on CFD method, the influences of suction strategies with different tip speed ratios on wind energy utilization rate, blade tangential force coefficient and flow field characteristics of wind turbines were studied, and energy consumption and wind turbine output power were comprehensively considered. The results show that the three control strategies can greatly improve the aerodynamic efficiency of the whole machine at low tip ratio. The optimal approach of alternating suction in the windward and leeward zones can significantly delay the separation point, delay the occurrence of dynamic stall of airfoil, and reduce the loss caused by periodic shedding of separation vortex. In addition, the strategy has a good control effect on the dynamic wake effect, reduces the torque fluctuation amplitude of the whole machine, eliminates the negative torque of the wind turbine under medium and low tip ratio, thus improving the energy efficiency and prolonging the service life of the wind turbine.
