This study applies a large-eddy simulation (LES) model to a street canyon in order to derive the fields of wind, turbulence, scalar concentration, concentration fluctuations, and scalar flux across the roof level. The wind blows at a right angle to the canyon axis and the emission is specified either as a line source with a constant emission rate along the street or as an area source with a constant concentration on the street and/or building surface, for which a wall function is introduced… CONTINUE READING
