摘要 利用CFD模拟手段,采用SST湍流模型封闭求解Reynolds时均方程方法,以高层建筑群风环境为研究对象,分析比较了六种典型平面布局下人行高度(2m)和空间位置的风速及涡场分布。结果表明,所有布局下近地位置的风速系数较大且沿高度变化显著,通道和立面转角区的风速增强效应沿高度有减小趋势;迎风前排布置单幢建筑的布局能减小人行高度的风速系数,其中斜向单排错开布局能减小风速系数的空间等值分布高度,但会出现最大尾流涡区。 利用CFD模拟手段,采用SST湍流模型封闭求解Reynolds时均方程方法,以高层建筑群风环境为研究对象,分析比较了六种典型平面布局下人行高度(2m)和空间位置的风速及涡场分布。结果表明,所有布局下近地位置的风速系数较大且沿高度变化显著,通道和立面转角区的风速增强效应沿高度有减小趋势;迎风前排布置单幢建筑的布局能减小人行高度的风速系数,其中斜向单排错开布局能减小风速系数的空间等值分布高度,但会出现最大尾流涡区。
