Pollution Dispersion in Street Canyon Under Traffic Induced Flow and Turbulence
Original language description
The paper deals with a computational model for traffic induced flow field and turbulence in a 3D street canyon. An Eulerian-Lagrangean model developed is presented that accounts for moving vehicles in several combinations of traffic lanes, one- or two-way traffic and different traffic rates. Moving vehicles are treated as a discrete phase using Particle-Source-In-Cell method. A Lagrangean momentum equation is solved for moving vehicles and additional momentum source is calculated for the momentum of continuos phase of ambiant air. Also several formulas for traffic induced turbulence are tested to show the influence on the flow field entrained into the street canyon. The street canyon is defined with an aspect ratio of W/H=1.27. As the results the velocity field in the mid-cross section of the canyon is presented showing the influence of traffic rate and one- or two-way traffic in two or four lanes.
