摘　　要：利用CFD软件Fluent 16.0,对直叶片H-Darrieus型水轮机模拟计算叶片桨距角为4°、8°、12°、-4°、-8°、-12°的定桨距情况,以及叶片按正弦模式及半正弦模式主动变桨,变桨幅值为4°、8°、12°的情况,重点对比两种桨距策略下水轮机能量利用率。结果表明,与正弦模式变桨水轮机相比,定桨距水轮机在实际应用中更具优势。半正弦模式变桨水轮机能量利用率提升显著,应重视定桨距策略在实际中的应用。In this paper,the CFD software ANSYS Fluent 16.0 is used to simulate a straight-bladed H-Darrieus turbine with preset fixed pitch angle of 4°,8°,12°,-4°,-8°and-12°,respectively,as well as active pitched blades in sinusoidal mode and halfsinusoidal mode,with the pitch amplitude of 4°,8°and 12°,with a focus on comparing the energy efficiency of the turbine under the two pitch strategies.The results show that compared with the sinusoidal-pitch turbine,the fixed-pitch turbine has more advantages in practical applications;the half-sinusoidal-pitch turbine has a significant improvement in energy efficiency;and the application of the fixed-pitch strategy should be emphasized in practical.
