摘　　要：与山地、草原以及开阔平原相比,城区或工业区的建设规划和建筑物本身的外形更为复杂多变,风流受到建筑物影响而产生的各种扰动使得风流模拟更为复杂困难,如高层建筑周围的狭管效应以及湍流强度计算等。本文结合实际案例,采用计算流体力学技术(CFD)对复杂城区风流场进行分析,以期更好地了解其风流属性,为风能评估、风电机组选型及选址奠定基础。Airflow simulation is more difficult in urban or industrial areas compared with conditions of mountains, grasslands and open plains. Especially, the shape of building and construction planning are more complex and it will disturb the airflow, such as the narrow tube effect around high-rise buildings. Using computational fluid dynamics technology, this paper analyses the airflow field in complex urban based on the actual case.
