摘要(Abstract)：

针对潮流能水轮机发电效率较低的问题，该文将格尼襟翼(Gurney flap, GF)流动控制理论引入潮流能水轮机叶片设计领域来改善水轮机叶片的水动力学性能，并开展GF及其参数对水轮机叶片水动力学特性的影响规律的研究。以NACA4418翼型作为研究对象，分别对基础翼型段和带GF的水轮机叶片翼型段建立三维模型，应用CFD数值模拟方法，研究了不同GF高度、弦向位置以及偏转角度对叶片翼型水动力学性能的影响。结果表明：翼型段上安装格尼襟翼能够有效提高升力系数，合理的GF参数设置可以有效地改善翼型段的水动力学性能，该研究中当GF安装在尾缘处且高度为3%C(C为弦长)、偏转角度为90°时，对翼型段改善效果最佳，其最大升力系数增加60.51%。
