为减弱叶尖扰流，改善螺旋型风力机叶片的气动性能，提出一种在螺旋型Darrieus3叶片垂直轴风力机对称翼型NACA0015叶片端部加装端板的设计方案。利用Fluent软件对加装端板前后的风力机叶片进行三维流体仿真，采用正交实验设计法及单因素实验法相结合的方法，研究端板的高度、形状和弦长对翼型气动性能的影响。研究结果表明：最佳的端板设计参数为高度48 mm(0.4c,c为叶片弦长)，长度168 mm(1.4c)，端板形状为和翼型同系列的对称翼型NACA0012，端板的高度和弦长过大和过小均不能有效降低阻力和提高风力机的效率。叶片两端添加合适尺寸的端板有助于减小叶尖扰流，改善风力机叶片叶梢附近表面的压力分布，有助于风力机稳定运行。
Abstract：To reduce tip turbulence and improve the aerodynamic performance of spiral wind turbine blades,a design scheme is proposed in which end plates are installed at the blade tips of a spiral Darrieus3 vertical-axis wind turbine with NACA0015 symmetrical airfoil blades.Three-dimensional fluid simulation of wind turbine blades before and after the installation of end plates were carried out using Fluent software. Orthogonal experimental design method and single factor experimental method were used to study the influence of three design parameters,namely height,shape and chord length of end plates,on aerodynamic performance of airfoil. The results show that the optimal end-plate design parameters are as follows :a height of 48 mm(0. 4c,where c is the blade chord length),a length of 168 mm(1. 4c),and a symmetrical NACA0012 airfoil of the same series as the end-plate shape. Excessively large or small end-plate height and chord length cannot effectively reduce drag or improve wind turbine efficiency. Adding end plates of appropriate size to both ends of the blades helps reduce tip turbulence,improve the pressure distribution near the blade tips,and contribute to the stable operation of the wind turbine.
