Abstract

A newly developed 2-d shallow layer model for dense gas dispersion in obstructed terrain is presented. The model solves the conservation equations of longitudinal and lateral momentum, dense gas mass and total mixture mass, averaged over the cloud height. Turbulence and diffusion are modelled by means of the entrainment velocity concept. The entrainment velocities are dependent on the ambient flow field and on the local cloud velocity. For model validation the Thorney Island 21 release was selected. In this field test 2000 nf of a mixture of Freon
