A comprehensive investigation of computational fluid dynamics (CFD) wind flow simulation with a 3D building model

The buildings can influence wind flow, while a better wind flow in a city will improve the air quality for the sustainable development of the urbanites. At present, Computational Fluid Dynamics (CFD) is commonly used for wind flow simulation. However, CFD simulation is able to focus only on a certai...

A comprehensive investigation of computational fluid dynamics (CFD) wind flow simulation with a 3D building model

At present, Computational Fluid Dynamics (CFD) is commonly used for wind flow simulation. However, CFD simulation is able to focus only on a certain height of a building. Hence, the 3D building model Level of Details (LoD) plays a vital role in the simulation. As regards the 3D building model standard, CityGML standard provides different LoD such as LoD1.0, LoD1.1, LoD1.2, LoD1.3, LoD2.0, LoD2.1, LoD2.2, LoD2.3, LoD3.0, LoD3.1, LoD3.2 and LoD3.3.
