阻力型垂直轴风力机聚风装置研究现状

摘要

Drag-type vertical axis wind turbine(DTVAWT)has the advantages of simple structure,low noise and independence of wind direction.However,its power coefficient is lower than other types of wind turbines.Thus,a lot of attentions have been paid on the wind augmentations or guiding devices which can improve its power coefficient and aerodynamic characteristics greatly.Many kinds of novel augmentations or guiding devices have been proposed all over the world.The objective of this paper is to summary those innovative devices through the discussion of the working mechanics and classification.This paper can provide valuable reference and foundation for the research of the DTVAWT.%阻力型垂直轴风力机具有结构简单、噪声小、不受来流风向影响等优点,但其功率系数较低.聚风装置不仅能有效提高阻力型垂直轴风力机的功率系数,还能改善其气动特性,故国内外学者对风力机外围的聚风装置做了大量的研究.文章详细描述了国内外阻力型垂直轴风力机聚风装置的研究现状,对其进行了分类整理和总结,旨在对阻力型垂直轴风力机的研究提供有价值的参考.
