带端板的螺旋型Darrieus3叶片垂直轴风力机的气动性能
Aerodynamic Performance of a Spiral Darrieus3 Vertical-Axis Wind Turbine with End Plates
摘要
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 enhance the operational stability of the wind turbine.关键词
