采用计算流体力学的方法,对不同平面、立面布局下高层建筑群周围的风环境进行模拟。确定由5座高层建筑组成的7种不同形式的平面布局,检验行人舒适度,分析不同风向下建筑物侧排风速的变化;研究两座串联布置的高层建筑的风场分布,分析建筑的高差、间距、宽度改变对目标建筑屋顶风速的影响。研究结果表明:不同风向下侧排风能最大的布局不同,0°风向时风能最大布局为反V型,最小为正V型;影响目标建筑屋顶风速的本质因素是前置建筑的来流分离点与目标建筑屋顶前沿连线与水平线所成的角度。从建筑环境中风能利用的角度,为城市规划以及高层小区建筑布局提供理论参考和依据。
Computational fluid dynamics (CFD) method was used to simulate the wind environment around the high-rise buildings under different layout and façade layout. Determine the layout of seven different forms of five high-rise buildings to test the pedestrian comfort and analyze the changes of building exhaust speed in different wind directions; study the wind field distribution of two high-rise buildings arranged in series and analyze the height of buildings Difference, spacing, width change of the target building roof wind speed. The results show that the maximum layout of exhaust air can be different under different wind directions. The maximum wind energy distribution at 0 ° wind direction is anti-V shape and the minimum is positive V shape. The essential factor affecting the roof wind speed of the target building is the separation of the flow from the front building The angle between the point and the roof of the target building and the horizontal line. From the perspective of wind energy utilization in the building environment, it provides theoretical reference and basis for urban planning and the layout of high-rise residential buildings.
