Numerical Study on Pollutant Dispersion in Urban Street Canyon

Abstract

The dispersion of car exhaustion in street canyon is studied by LES and unsteady RANS. Both velocity field and distribution of pollutant concentration are computed. The influence of the geometry of building blocks on the pollution is investigated.
