摘　　要：利用CFD(计算流体力学)技术模拟居住区内的风环境。针对同济新村部分建筑和同济设计中心A楼,以上海市多年的平均气象环境作为初始条件,结合CFD软件(Air-pak)对风绕过居住区建筑时的流场进行了模拟分析。通过模拟结果分析狭管风、风影区等在建筑物周围分布的特征以及将产生的影响。研究结果表明,运用CFD技术进行居住区规划设计的大气流场模拟分析,具有实际应用价值,并对居住区的风环境规划具有指导意义。In this paper,we use CFD(Computational Fluid Dynamics)technology to simulate the wind environment in residential area.For part of Tongji Village and Building A of Tongji Design Center,we use the average weather conditions of Shanghai as the initial conditions,combined with CFD software(Air-pak)to simulate and analyze the flow-field of residential area when the wind flows around buildings.The distribution characteristics of the slot wind,wind shadow zone around the building as well as its impact are analyzed through the simulation results.The research results show that the CFD technology used in flow field simulation analysis in residential areas has a practical value and has guiding significance for wind environmental planning of residential area.
