Seasonal Changing Effect on Airflow and Pollutant Dispersion Characteristics in Urban Street Canyons
In this study, the effect of seasonal variation on air flow and pollutant dispersion characteristics was numerically investigated. A three-dimensional urban canopy model with unit aspect ratio (H/D = 1) was used to calculate surface temperature distribution in the street canyon. Four representative time events (1000 LST, 1300 LST, 1600 LST and 2000 LST) during typical clear summer and winter da...

متن کاملFlow and Pollutant Dispersion in Urban Arrays for the Standardization of Cfd Modelling Practise
The study of the effect of obstacles on flow and dispersion in the atmospheric boundary layer is one of the most important topics in atmospheric dispersion research. Computational Fluid Dynamics (CFD) methods are increasingly used to predict concentration fields near buildings in an operational context, but extensive validations are still needed. In this paper, we analyse the effect on flow and...
متن کاملthermal effect on pollutant dispersion in an urban street canyon
his investigation was carried out to reveal the impact of solar radiation on wind flow structure and pollutant dispersion in an urban street canyon of aspect ratio of one using the computational fluid dynamic (cfd) technique. the simulation results (velocity and concentration data) show that heating from building wall surfaces and ground lead to strong buoyancy forces as the air is heated by th...
متن کاملNumerical and Physical Modeling of Bluff body Flow and Dispersion in Urban Street Canyons
To develop reliable computer models for the bluff body flow and transport of pollutants or chemical and biological (CB) agents in urban environments requires accurate measurements of the basic flow fields for carefully controlled, well-known conditions. Fluid modeling in an Industrial Wind Tunnel provides an opportunity to produce accurate simulations of the bluff body flow and transport of urb...
