Numerical sumulation of pollutant dispersion from vehicle exhaust in street configurations

Abstract

The impact of the street configurations on pollutants dispersion from vehicles exhausts within urban canyons was numerically investigated using a computational fluid dynamics (CFD) model. Three-dimensional flow and dispersion of gaseous pollutants were modeled using standard kappa - epsilon turbulence model, which was numerically solved based on Reynolds-averaged Navier - Stokes equations by the commercial CFD code FLUENT.
