Abstract: The paper presents an overview of the influence of street architecture on the wind and turbulence patterns in street canyons and discusses the effects on local air quality. The findings of recent experimental and numerical studies are summarized and wind-tunnel data sets are presented that illustrate the flow-field variability. It is shown that small-scale features of the street architecture play an important role. The formation of a vortex inside the street canyon is affected by the roof configuration. In shorter street canyons, the flow component along the street becomes important for pollutant transport. These results are of importance for urban air quality modeling in particular when dealing with pollution problems caused by road traffic. Furthermore, the findings should be taken into account in fast response models that are used to assess critical areas in the case of accidental or non-accidental releases of hazardous material in urban areas.

TL;DR: In this paper, the authors present a methodology that combines on-street and laboratory measurement with modelling of the movement of air, vehicles, and vehicle exhaust emissions to assess the sustainability of urban road transport in terms of exposure to traffic-related air pollution.

TL;DR: In this paper, the authors investigate the re-entrainment of pollutants around a low-rise industrial building under opposing cross winds through experimental means in a wind tunnel and find that the maximum re-enrainment always occurred near the two ends of the building, where the pollutants mostly flowed around the ends rather than over the roof.
