Simulation and Analysis of the Blade Shape of Savonius VAWT

Abstract

随着可再生能源使用的发展,风电已成为世界上最为主要的能源输出之一,其重要性也受到日益重视。叶片是风力机的一个重要的组成部分,它的形状对风力机吸收风能的效率起着至关重要的作用。本课题以厦门市人事局留学人员回国择优资助项目《垂直轴微风风力发电系统的设计》为背景,主要研究小型家用垂直轴风力发电机叶片的设计,优化及计算机模拟。主要研究成果如下: 1.风力机叶片的设计 (1)探讨叶片设计的通用方法。综合国内外多种叶片设计方法,整理现有叶片设计模型理论,得出一种简单有效的、非传统形状的风力机叶片的设计方案。利用机械设计软件CATIA对叶片的形状建模,在流体工程模拟软件FLUENT中对其进行模拟分析。 ...With the development of the recycle resource, wind power becomes one of the most important renewable resources in the world, especially when the environment is badly polluted and the conventional resource is drying up. More and more attention is being paid to the wind energy for its particular merits, which is recognized by the whole world by its cleanness and recycle characteristics. Blade is on...学位:理学硕士院系专业:物理与机电工程学院物理学系_凝聚态物理学号:2005130164
