Abstract

An evaluation study of the Local Scale (CFD) dispersion model ADREA-HF has been performed, by applying the SMEDIS Project evaluation protocol. The model validation for continuous releases, under neutral atmospheric conditions, strong density effects and with or without complex effects (obstacles, aerosols) has been based on the EEC-55 propane experiment. Detailed experimental information on EEC-55 was obtained from the SMEDIS experimental database. The predicted mean concentrations at the experimental sensor positions are compared against the experimental, using various statistical measures. It was found that the model concentration predictions are in good agreement with the experimental data, giving a 70% factor of 2 for the unobstructed case (EEC-550) and an 80% value for the obstructed case (EEC-55 1). The predicted average te
