| 摘 要： | 为了提高H型风轮的自启动性能,探索性地设计了一种仅有前缘和一个翼面的新颖翼型,并对采用该翼型的H型风轮进行风洞试验,分别测试了H型风轮在多个风速下的空载启动性能和功率输出特性,分析了雷诺数效应及翼型对于不同实度风轮的适用性.结果表明:采用新颖翼型的H型风轮能够低风速启动,具有较好的启动性能,该翼型对于提高大实度风轮的启动性能尤其明显;采用该翼型的大实度风轮以阻力为主要驱动力,本质上属于阻力型风力机,然而具有较高的风能利用系数.综合启动性能和功率输出特性,文中设计的翼型适用于大实度H型风轮.

| Abstract: | In order to improve self-starting capability of H-type wind turbines, a novel airfoil containing just leading edge and one airfoil surface was designed exploratively, and wind tunnel experiments on the wind turbine rotor with this airfoil were carried out to investigate the start-up behavior and power output characteristics at different wind speeds. Effects of Reynolds number and solidity on aerodynamic characteristics of the turbine rotor were clarified. The experimental results indicate the turbine rotor adopting the novel airfoil is capable of self-start at low wind speeds, exhibiting an excellent self-start behavior, especially for the turbine rotor with large solidity. In addition, the turbine rotor with large solidity is mainly driven by the drag and essentially belongs to drag-type wind turbine, but it is subject to a relatively high power coefficient. Considering the self-start behavior and power output characteristics, the proposed airfoil is more suitable for the H-type wind turbine at large solidity. |
