摘要
以翼型为NACA0012的单叶片H型垂直轴风力机为研究对象,采用数值模拟的研究方法,分析叶片两端未安装小翼和安装3种不同叶尖小翼对H型垂直轴风力机叶片表面压力分布和叶尖涡的影响。结果表明:安装小翼均可提高H型垂直轴风力机的最大转矩系数,其中安装Winglet可提高H型垂直轴风力机起动力矩;增加叶尖小翼均对消除叶尖涡有利;H型垂直轴风力机叶片两端安装Winglet小翼较其他两种小翼效果好。
Base on a single blade NACA0012 airfoil H type vertical axis wind turbines （H-VAWT）as the research object, and adopting the method of the numerical simulation to analysis blade surface pressure distribution under two different conditions and tip vortex of H-VAWT that are installed three different kinds of tip vanes on both ends of the blade and not installed. The results showed that the installed tip vanes can improve the maximum torque coefficient of H-VAWT, especially, the start torque of H-VAWT can be improved when installed Winglet; Installed tip vanes takes advantage of eliminating tip vortex ; Compared with other two kinds of tip vanes, installed Winglet on the ends of H-VAWT blade is the more well effect.
