Abstract
Turbulent diffusion of gaseous contaminant near a cubic-shaped buildin g model is predicted by LES using a Dynamic Mixed SGS (DM) model with the aid of the composite grid technique. The results obtained using a composite grid show better agreement with experiment than does the cas e using a single grid, Some discrepancies from the experimental result s are observed in the results of the standard Smagorinsky model with a composite grid. These discrepancies are improved remarkably by using the DM model.
