基于CFD不同布局下的高层建筑群风环境模拟

Wind Environment Simulation of High-Rise Buildings Based on Layouts of CFD

针对高层建筑群因为不恰当建筑布局导致的恶性气流问题,及对高层居住区居民日常生活造成的困扰。研究6幢方形高层建筑组成的建筑群周围的风环境特征,利用FLUENT软件模拟不同建筑布局下的气体流动特点。通过对比、分析不同建筑布局下室外人行高度(1.5 m)处的风速云图和风速矢量图,得出建筑布局与风环境优劣之间存在的关系。

Aiming at the malign airflow problem caused by improper building layout of high-rise buildings and the troubles caused to the daily life of residents in high-rise residential areas, wind environment characteristics around 6 square high-rise buildings were studied, and the software FLUENT was used to simulate gas flow characteristics under different building layouts. By comparing and analyzing the wind speed cloud map and wind speed vector map at the outdoor pedestrian height (1.5 m) under different building layouts, the relationship between building layout and wind envi-ronment was obtained.
