The flow and diffusion fields in the urban canyons were examined for three street configurations: (1) Regular-shaped intersection, (2) T-shaped intersection and (3) Skew-shaped intersection. Details of the flow and dispersion field were reported that includes the structures of the mean flow field, turbulence intensity, turbulent kinetic energy, Reynolds stress and concentration of pollutant emissions.
