基于数值风场的高层建筑对临近低层建筑群影响分析

Analysis on Wind Field around Low-Rise Buildings Impacted by High-Rise Buildings

针对高层建筑对低层建筑的风压、风速分布的影响问题,选用标准k-ε湍流模型,应用CFD数值方法模拟高层建筑影响下的低层建筑群的风场,侧重模拟分析了高层建筑的位置布局改变对低层建筑群风速及风压场的影响。分析结果表明:高层建筑对临近低层建筑群风场的影响显著,高层建筑的位置对低层建筑群风环境的影响较大。

High-rise buildings always affect the wind pressure and wind speed distribution of low-rise buildings.Regarding this problem,by using the standard k-ε turbulence mode and applying CFD numerical method to simulate the wind field around the low-rise buildings on the impact of high-rise buildings,this article focus on the wind speed and wind pressure field around low-rise buildings,which is affected by the location of high-rise building.The results show that：the impacts of wind field around low-rise buildings which is near the high-rise building are significant,the wind environment around low-rise buildings are obviously affected by the location of high-rise building.
