为了解适用于城市绿地风场的数值模拟方法,选用了FLUENT软件和城市街谷大气动力模式分别对城市中某建筑周围的风场进行了模拟分析。实例表明,上述软件与模式都能正确模拟出建筑周围风场的基本特征,其中FLUENT软件对局部风场细节描述更为详细;而在较大区域的风场模拟上,城市街谷大气动力模式数据前处理相对灵活,在将来的风场模拟方面具有较强的应用价值。
為瞭解適用于城市綠地風場的數值模擬方法,選用瞭FLUENT軟件和城市街穀大氣動力模式分彆對城市中某建築週圍的風場進行瞭模擬分析。實例錶明,上述軟件與模式都能正確模擬齣建築週圍風場的基本特徵,其中FLUENT軟件對跼部風場細節描述更為詳細;而在較大區域的風場模擬上,城市街穀大氣動力模式數據前處理相對靈活,在將來的風場模擬方麵具有較彊的應用價值。

In order to learn the numerical simulation approach suitable for urban vegetation,the FLUENT software and Urban Street Canyons Atmospheric Dynamics Model（UCD） were applied to wind field simulation around a building respectively.The final model results show that both of the FLUENT software and UCD could describe the basic characteristics of wind field around a building,in which FLUENT gave a more detailed description of local region.However,as data pre-processing is easy to be applied in larger area,it is believed that the Urban Street Canyons Atmospheric Dynamics Model will play more important roles in the coming years,especially in dealing with wind environment.
