摘要

化石燃料的枯竭和对全球变暖的日益关注迫使社会思考环境友好型能源。在这方面,风能是一个可行的选择。垂直轴风力涡轮机提供了很有前途的解决方案,从而减轻了社会对综合电网系统的依赖。小型城市屋顶垂直轴风力发电是一种应用广泛、结构简单的风力发电形式,其设计和开发必须符合成本效益要求。对三直叶片VAWT进行了研究。该设计是利用现有的经验公式和复杂的软件制定的,从而制造出一个按比例缩小的原型。为了优化涡轮的性能,对多种支板配置、中心柱组件、叶片剖面进行了详细的CFD和应力分析。对分析结果、软件计算结果和实验结果进行了比较。

Optimized design of a straight blade urban roof top vertical axis wind turbine
Depletion of fossil fuels and increasing concerns of global warming has forced the society to think about environmental friendly energy resources. Wind energy is a viable option in this regard. Vertical axis wind turbines offer promising solution and hence relieving the society from the integrated grid systems. Small scale urban roof top vertical axis wind turbine (VAWT) is one of the simplest forms with its wide spread applications necessitating its design and development in a cost-effective manner. A study is undertaken on a three straight bladed VAWT. The design is formulated using available empirical formulas and sophisticated software's leading to a fabricated scaled down prototype. A detailed CFD and stress analysis is done on multiple struts configurations, central column assemblies, blade profiles to optimize the performance of the turbine. A comparison is also made between the analytical, software based and experimental results.
