Impact of Urban-Area Geometry on Pollution Ventilation

Popis výsledku v původním jazyce

In order to quantify the influence of building geometry on the vehicle pollution ventilation within street canyons, a wind tunnel experiment and a large eddy simulation (LES) was performed. A model of an idealised urban area with a line source was designed with different building arrangements. Concentration, horizontal and vertical advective and turbulent pollution fluxes were computed from the measured data as ventilation characteristics. A domination of advective pollution transport was determined within street canyons. The turbulent transport was significant in vertical direction within as well as above the built-up area. The ventilation intensity was evaluated for each model arrangement separately.
