摘要
城市的风热环境研究对于理解城市热岛效应、制定节能减排措施与改善气象环境有重要意义。以建筑密度高、超高层建筑密集的广州中心城区为例,统计了建筑和交通人为热释放值,并以此作为风热环境模拟的热量输入条件。利用Rhino构建建筑三维立体模型,在CFD中进行不同高度面风热环境的模拟。建筑单元由于建筑属性、人为释放热的差异,风热环境明显不同,特别表现在城中村和商务中心两类建筑上。
The research on urban wind-heat environment is of great significance for understanding the urban heat island effect,formulating energy-saving emission reduction measures and improving living environment.Taking the central urban area of Guangzhou with high building density and dense super high-rise buildings as an example,the anthropogenic heat release values of buildings and traffic are calculated and used as heat input conditions for wind-heat environment simulation.Use Rhino to build a three-dimensional model of the building,and simulate the wind and heat environment at different heights in CFD.The simulation shows that due to differences in building density and function,different building types have differences in the wind and heat environment,especially in urban villages and business centers.
