摘要
性能优越的垂直轴风力发电机正越来越受到关注。优良的风叶是使垂直风力发电机获得最大风能利用系数和良好经济效益的基础。垂直风力发电机叶型的气动性能研究是当前叶片设计的重要内容。利用ANSYS FLUENT12.0对NACA4412、FX76MP12、DU86-137-25以及C型四种不同叶片的气动性能进行了仿真和分析,得出C型叶片相对其他三种叶片有着更好的气动性能,能为垂直风力发电机叶片的设计起到指导作用。
Now researchers of many countries are paying more and more attention to the vertical-axis wind turbine for its superexcellent performance.Excellent wind turbine blade is the foundation to get the most wind power coefficient and economic efficiency of the vertical-axis wind turbine.Research the aerodynamic performance of the vertical-axis wind turbine blade is the important content of the blade design at present.Use ANSYS FLUENT12.0 to simulate and analysis the aerodynamic performance of four different kinds of blades such as NACA4412,FX76MP12,DU86-137-25 and C,and conclude the C-shaped blade with a better aerodynamic performance compared with other three kinds of blades.The conclusion can play a guiding role in the design of the vertical-axis wind turbine blade.
