摘要/Abstract

摘要： 为了研究涡流发生器(VGs)与翼刀组合对风力机叶片气动性能的影响,以NREL Phase VI风力机叶片为模型,采用CFD方法分别对加装单双VGs、单双翼刀及其组合共8种流动控制方式进行模拟,分析在风速不同时对风力机叶片气动性能的影响.结果表明:单VGs与单翼刀组合、双VGs与单翼刀组合不仅能获得更高的输出扭矩,而且能更有效地抑制叶片弦向和展向的流动分离;单VGs与单翼刀组合、双VGs与单翼刀组合可将两装置的优势相结合,展现出更好的流动控制效果;双VGs与单VGs相比能进一步延缓流动分离.

Abstract: In order to study the effect of vortex generators (VGs) and blade combinations on the aerodynamic performance of wind turbine blades, the NREL Phase VI wind turbine blades were taken as models. The CFD method was used to simulate eight flow control configurations, including single and double VGs, single and double blades, and their combinations. The impact of these configurations on the aerodynamic performance of wind turbine blades under different wind speeds was analyzed. The calculation results show that the combinations of single VGs with single blade, as well as double VGs with single blade not only obtain higher output torque but also more effectively inhibit the flow separation in the chord and span directions of the blade. These combinations combine the advantages of both devices, demonstrating better flow control effect. Furthermore, compared with single VGs, double VGs can further delay flow separation.

Key words: NREL Phase VI wind turbine, vortex generator, wing knife, aerodynamic performance
