Abstract
The turbulent diffusion of gaseous contaminant near a building model is predicted by Large Eddy Simulations (LES) using a Dynamic Mixed SGS model (DM model ) with the aid of the composite grid technique. The results using a composite grid show better agreement with the experiment than does the case using a single grid. Some discrepancies from the experimental results are observed in the results of the standard Smagorinsky model (S model) with a composite grid. These discrepancies are reduced remarkably by using the DM model.
