摘要/Abstract

摘要： 在升力型立轴风力机的叶片旋转一圈中,两方位角叶片的攻角为零,产生为负值的刹车力矩,需要消耗其他叶片的正功来克服此力矩,进而降低了风力机整体性能。提出采用干扰气流来改善零攻角区域叶片周围流场,进而提高升力型立轴风力机气动性能的新方法。以美国Sandia国家实验室旋转直径2 m的Φ型风力机为研究对象,基于多流管模型,分析干扰气流对位于赤道半径R、0.8R和0.6R叶素的攻角、切向力、法向力的影响规律。计算结果证明,在干扰气流的影响下,两零攻角方位角的攻角、切向力和法向力均有明显提高;在180°旋转角,叶素的攻角、切向力以及法向力增幅,随着旋转半径的减小而增大。以上研究结果证明干扰气流有效地改善了零攻角区域叶片的气动特性。

Abstract: Within the path circle of lift-type vertical axis wind turbine(VAWT), two azimuth angle whose attack angle of blade is zero create negative brake torque, which need positive power to overcome and greatly lower the whole performance of wind turbine. A new technology that an interference air is used to rebuilding the flow field of blade with zero attack angles is put forward to promote power output. USA Sandia experimental Φ-type VAWT with 2 m diameter and 2 m height is researched as object. Research on the effect of interference air on attack angle, tangential force and normal force of blade element in equatorial R, 0.8R and 0.6R, are conducted based on multiply stream-tubes model. The calculation results showInterference air greatly promote the performance of blade element at two azimuth angle from a zero value to a high positive value; further, in 180° rotation angle the extent of effect is increased with blade element diameter decreasing. These results prove that the interference airflows are able to effectively promote the aerodynamic characteristics of two zero attack angle regions.
