建筑环境中的风能利用

Study of wind energy utilization in the architecture environment

城区建筑环境中的风场有紊流加剧、风速降低的特点。因此,风力强化和集中的问题需要得到解决。目前有非流线体型、平板型和扩散体型3种空气动力集中形式。文章应用CFD数值模拟软件分别对3种基本空气动力集中建筑模型的风速进行了模拟计算,探讨了最佳的风能利用形式。

Due to the interference of buildings, wind veloaty becomes low and turbulent level is higher in urban, aerodynamic concentrators are formed. At present there are three basic midels for aerodynamic concentrators： diffusers, flat plate concentrators, and the bluff body. This paper attempts to analyze performances of the concentrators using CFD simulation software, to discusses the optimal wind energy application.
