Original abstract
An Eulerian-Lagrangian method developed for road tunnels has been further extended and modified for pollutants dispersion in street canyons and cross roads. The method is based on CFD modelling and accounts for moving vehicles and by them induced flow and turbulence. The team has been focusing on both theoretical advancement of the aforementioned method and onto applications to actual city areas. The theoretical development was oriented mainly to model dynamic situations of "Stop-And-Go" in intersections. The model was applied to real situations in the city intersection in the city of Brno and in the frame of an excercise also to a street structure in Hannover in Germany (Podbielski strasse). The prediction was compared with field measurements.
