Application of Advanced. Turbulence Models in Determining the Structure and Dispersion of Heavy Gas Clouds

The present paper reviews the use of a particular form of higher order turbulence modelling in heavy gas dispersion, and demonstrates its potential for use in complex situations. It is also shown how such models can be used to provide more general information on the detailed turbulence structure within a heavy gas cloud. A currently available 3D heavy gas dispersion model is also described, and examples given of typical applications.
