Modelling of Traffic Pollutant Dispersion Released from Singel Line Source in Local Urban Areas

Dispersion of pollutants from the major traffic path in direction perpendicular to the traffic path is very important parameter enabling the prediction of air pollution concentration in the all small-size urban area. Numerical modelling (CFD code StarCD) was used as the computational code for carried out studies. The Eulerian approach of the particle dispersion modelling was engaged. The parametrical study was focused on assessment of the PM10 dispersion from line sources surrounded by the buildings with various configurations. The relation of PM10 concentration and perpendicular distance from the line source was used for evaluation of the PM10 dispersion intensity.

Šíření znečištění z významných dopravních cest ve směru ve směru kolmém na dopravní komunikaci je velmi významný parametr v městské zástavbách. Numerická silulace metodou CFD byla použita pro parametrické studie věnované intenzitě disperze částic PM10 při vzdalování od komunikace.
