AbstractThe correlations among air exchange rate (ACH), pollutant exchange rate (PCH) and friction factor (f) are proposed to evaluate the performance of ventilation and pollution removal of street canyons of different building-height-to-street-width (aspect) ratios (ARs) and building shapes in this paper. Hypothetical urban areas were simplified to computational domains consisting of idealized two-dimensional (2D) street canyons and the Reynolds-averaged Navier-Stokes (RANS) equations with the Renormalization Group (RNG) k-є turbulence model were adopted in the mathematical modelling. It is found that the turbulent components of ACH and PCH are closely related to f while their mean components are rather extraneous.
