摘　　要：为了研究亚热带气候条件下建筑群的室外风环境,以广州地区自然气候条件为基础,以可压缩空气为研究对象,建立了不同布局建筑群的物理和数学模型,并应用CFX软件模拟了建筑群的室外稳态湍流流场,结合得到的速度场、压强场和WBGT值,分析比较了不同布局建筑群的室外风环境,得到了最大风速区域和涡旋产生区域,确定了最佳的建筑布局,并对风环境恶劣的区域提出了改善措施.According to the climate characteristics in Guangzhou and regarding the compressiable air as the object of study, this article established the physical and mathematical models of different building group distributions in order to study the outdoor wind environments of building groups in the subtropical climate. It also simulated the steady turbulent field of outdoor building groups by means of the CFX software. Moreover, it analyzed and compared the wind environments of different building group distributions combined with the velocity field, pressure field and WBGT value. Then it obtained the area of maximal velocity value and the area of existing vortex so as to choose the best building group distributions. In the end, it presented the ameliorative suggestions for the abominable environment.
