This paper reviews recent studies pertaining to flow and pollutant dispersion around buildings and complex geometries (real cities). Field/laboratory experiments and numerical simulations (mainly Computational Fluid Dynamics, with attention to Large Eddy Simulation approach) performed by us as well as by other researchers who have looked at flow, turbulence, dispersion and ventilation around bluff bodies are considered. We attempt to review state of the art results considering that the urban complexity is not only due to the packing density, but also spatial building-height variability, thermal properties, the presence of vegetation. These findings are discussed in light of recent advances of operational urban dispersion models.

Abstract
This paper reviews recent studies pertaining to flow and pollutant dispersion around buildings and complex geometries (real cities). Field/laboratory experiments and numerical simulations (mainly Computational Fluid Dynamics, with attention to Large Eddy Simulation approach) performed by us as well as by other researchers who have looked at flow, turbulence, dispersion and ventilation around bluff bodies are considered. We attempt to review state of the art results considering that the urban complexity is not only due to the packing density, but also spatial building-height variability, thermal properties, the presence of vegetation. These findings are discussed in light of recent advances of operational urban dispersion models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
