Original Abstract
A 3-D Eulerian-Lagrangian approach to moving vehicles is presented that takes into account the traffic induced flow rate and turbulence. The method is applied to pollutants dispersion in an individual street canyon and the system of two street canyons forming a perpendicular intersection. The approach is based on CFD calculations using Eulerian approach to continuous phase and Lagrangian approach to moving vehicles. Speed of wind was assigned values of 4, 7 and 12 m/s. One-way and two-way traffic with different traffic rates per lane is considered. In case of intersection, longitudinal wind was assumed. Predictions show differences in the pollutants dispersion in case of one- and two-way traffic.
