摘要

屋顶安装小型风力发电机是近几年来新发展的一种风能利用形式。以年平均风速为对象，研究建筑屋顶风能利用的效能，提出衡量建筑风能利用效能的6个性能指标。利用CFD数值模拟方法分析了长方体建筑平屋顶对风能的利用效果，考察了不同迎风角下控制点的性能指标，探讨屋顶风力机安装的最佳位置和排列形式。对长方体建筑屋顶形式进行分析，对比了4种不同屋顶形式的风能利用效能。

Abstract

Installing small wind turbines on the roof of buildings is a new way of wind power utilization in recently years. Based on the annual mean wind speed

the efficiency of wind power utilization on roofs of buildings was studied and the evaluation indexes for the utilization efficiency were proposed. With the help of CFD numerical analysis

the analysis on wind power utilization efficiency on flat roofs of rectangular buildings was carried out. The performance indexes of reference points under different windward angles were investigated. The best position and arrangement of wind turbines on the roof were also discussed. Furthermore

the utilization efficiency of four roofs with different shapes were analyzed and compared with that of flat roof.
