Abstract Pollutant dispersion in urban street canyons has been widely investigated by large-eddy simulation (LES). Many LES studies focused on generic under a wind direction perpendicular to the axis. Accurate simulations require sufficiently large domain size minimize effects of artificial boundary conditions at faces results. As opposed RANS simulations, there is lack guidelines for an approp...

Road vehicles are a large contributor to nitrogen oxides (NOx) pollution. The routine roadside monitoring stations, however, may underrepresent the severity of personal exposure in urban areas because long-term average readings cannot capture effects momentary, high peaks air While numerical modelling tools historically have been used propose an improved distribution ultra-high resolution Compu...
