Air Pollution Dispersion in Segments of Urban Areas

Popis výsledku v původním jazyce

The paper presents results of numerical calculation of pollutants dispersion in segments of urban areas. Geometry of the typical segments of urban area was transformed in numerical models built up from hexagonal finite elements. The solution domains represent areas of 1 x 1 km. Traffic is considered as the primary source of airborne particles. Dispersion of pollutants from the traffic path in direction perpendicular to the traffic path is monitored as important parameter for subsequent simplified prediction of air pollution concentration in urban areas. Deposition of particles is described by inclusion of Brownian diffusivity and eddy diffusivity in close vicinity of the surfaces. The relation of PM10 concentration and perpendicular distance from the line source was used for evaluation of the PM10 dispersion intensity. Numerical modelling (CFD code StarCD) was used as the computational code for carried out studies. The Eulerian approach of the particle dispersion was engaged. The param
