A study of heat transfer effects on air pollution dispersion in street canyons by numerical simulations

0
This study investigated thermal effects on the flow and dispersion of pollutant in urban street canyons. A heating module was introduced into the micro scale model MIMO for describing the thermal exchange between the air in the street and the buildings. Furthermore, the influence of wall temperatures and building shading on the in-street flow and its vertical transport is discussed. Results from numerical simulations that are performed with MIMO are compared with corresponding results from numerical simulations performed with the commercial CFD code CFX-TASCflow.
