| Abstract: | The air flow and pollutant distribution in typical street canyons under different forms of Viaducts are modeled using the CFD（computational fluid dynamics）software of FLUENT.The different forms of the viaduct include the height of the viaduct,the width of the viaduct and whether there is a pollution source on the viaduct.Air flow and dispersion of pollution are modeled using the standard k-εturbulence and discrete phase models,and the viaducts impact on the wind field and pollutant diffusion are calculated. |
