城市绿地风场的不同数值模拟方法比较研究

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 building in respectively, the final model results show the both can describe the basic characteristics for wind field around building, in which FLUENT can give 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 role in the coming years, especially in dealing with wind environment.
