Abstract

The main objective of the project has been the validation of a series of heavy gas dispersion models by means of the Thorney Island large scale releases. The large variety of models published in the literature has been reduced, to such models which are frequently used and differ significantly in their basic assumptions. The experimental data of 15 instantaneous heavy gas releases at Thorney Island have been processed. Comparison calculations have been performed for nine characteristic experimental data sets. The results show good agreement for the downwind distance profile of the concentration at ground level for a number of models. Large differences in shape and absolute value of the concentration profiles are obtained for elevations from 2.4 m up to 6.4 m. Some main model deficiencies have been identified. Recommendations for the applicability of the different models are given.
