Concentration and flow distributions in urban street canyons: wind tunnel and computational data
The goal of this paper is to present bluff body flow and transport from steady point sources of pollutants, or chemical and biological agents in an idealized urban environment This paper includes ventilation behavior in different street canyon configurations. To evaluate dispersion in a model urban street canyon, a series of tests with various street canyon aspect ratios (B=H) are presented. Bo...
متن کاملDynamical Modeling of Stochastic Wind Flow in Street Canyons
For decades, the borders of building studies were restricted up to the exterior walls. With better understanding the side effect of urbanization on human health and with excessive progress in new investigation tools, the area of building studies were enlarged to neighborhood environment where mass and air transport vividly interacts with the buildings. Unlike the indoor studies, one can emphasi...

متن کاملNumerical Simulation of Wind Flow and Pollution Transport in Urban Street Canyons
In this study, a three-dimensional numerical simulation of the wind flow and pollutant transport in street canyons is carried out by a new specific solver, which is developed and coupled into an open source CFD tool box, the OpenFOAM package. The new model has been applied to study the effect of roof shapes and building heights on the flow patterns and pollutant transports in the street canyons...
متن کاملVentilation efficiency of street canyons with intersections
When looking at domains with several building densities, the resulting average concentrations caused by traffic when unknown, are often linearised between known building densities. To verify if this assumption is correct, several cases of street canyons with intersections, are simulated using the DALESURBAN model. The traffic is represented by a constant emission line source spanning the entire...
