A dense vapour dispersion code package for applications in the chemical and process industry
A computer code package for dispersion of dense vapour clouds in obstructed terrains is presented. The package consists of three models: a detailed fully three-dimensional model and two models (1-D and 2-D) based on the shallow layer concept. The models are validated by the application of three field tests with different degrees of geometrical complexity. The first test was performed on flat terrain under isothermal conditions. The second was a cold jet release with a straight fence perpendicular to the flow. In the last test a semi-circular fence obstructed the flow. The validation exercise indicated that the dimension of the model applied should preferably be of the same order as the geometry to be described.
