【摘要】 根据对城市住宅小区布置形式与空间拓扑特征的研究,建立了适用于城市住宅小区大气环境效应评估的分析模型.利用CFD软件对分析模型在不同风向角时建筑环境内的风速分布状况进行了数值模拟.并重点分析了行人高度的风环境状况.结果表明,当风向角为135°时建筑的风环境较为良好;在建筑设计时应尽量避免风速变化较大的地方成为人流活动较多的地方.更多还原

【Abstract】 According to the analyses of the layout of urban residential areas and topological space characteristics,it establishes a model for the assessment of atmospheric environment in urban residential areas.CFD software was used to numerically simulate the wind velocity distribution from different angles.The wind environmental conditions were analyzed from the perspective of the pedestrians.The experimental results show when the angle of the wind is 135 °,the wind environment is better,and that in architectural design,places where the wind speed changes greatly are not suitable for more human activities.更多还原
