Behavior of Particulate Matter Produced by Cars in a Regional Model of Urban Canopy Layer

This paper introduces the utilization of the CFD technique for the modeling of PM10 (particulate matter 10 μm) behavior in urban areas, focusing on a description of the processes in the ground surface boundary layer. A description of the deposition and resuspension processes is introduced and applied to the regional numerical model of the city of Brno. The threshold velocity of re-suspension was obtained from the small scale modeling of PM10 dispersion in a street gully located inside the regional model. The predicted concentration fields were compared with theoretical studies and an in-situ measurement.

Keywords: particulate matter, numerical modeling, urban area
