| Abstract: | The present paper discusses the development of a transport phenomena model for the dispersion of heavy gases. It describes the three-dimensional transient dispersion processes of an accidentally released contaminant. The model accounts for heavy gas effects and allows one to explicitly resolve the effect of twodimensional buildings in the ambient flow field. The results of the simulation are compared with those of other calculation procedures for conditions where the different approaches are applicable. In addition, comparisons are made with results from field experiments on heavy gas dispersion. |
