With the energy crisis intensified and peoples increasing awareness of environmental protection,wind energy as one of the clean,non-polluting and renewable energy sources,has attracted world high attention.Wind energy utilization in the building environment has the advantage that it can avoid transporting cost,especially for residents without electricity.Considering wind energy utilization around buildings,especially the flat roof type,this paper presents the analysis of a three-dimensional wind field around buildings including a CFD numerical simulation method.By simulating the wind with different directions and different speeds,the characteristics of the wind field around a single flat roof building and two identical flat roof buildings were analyzed.It investigated the distribution of wind in two aspects,namely,the wind speed and turbulence intensity.The wind energy efficiency of the flat roof was also analyzed.Considering the wind speed,wind direction,and turbulence intensity,the best position to install the wind turbine on flat roofs is also discussed in this paper.

以低调的方式奢华 奢华并不总是以炫目的姿态出现在我们面前。面对一个多变的不确定世界，谦虚和内省显得格外重要。而奢华也开始变得更低调。这幢别墅色彩以大自然的色彩棕黄色系为主，深深浅浅点缀其中，拉伸了空间层次感；欧式风格的家具华丽淡雅，配以半透明的落地白纱，和煦的阳光就这样散落开来，让身在其中的人在暖暖的温馨中感受着淡淡的奢华气息。
