Abstract: The three-dimensional microscale numerical model MIMO was applied to calculate the dispersion of a passive pollutant in the vicinity of a U-shaped building. Three different locations of a non-buoyant source and six different wind directions were examined. The calculated concentrations were compared with concentrations measured in a boundary layer wind tunnel. The comparison shows a very good agreement between numerical and wind tunnel results.

Keywords: MIMO models; passive pollutants; U-shaped buildings; building effects; air pollution; environmental pollution; modelling; atmospheric dispersion models; boundary layer; wind tunnels.
