Özet
The results for the atmospheric dispersion simulations following an accidental release in an industrial site at Bourges area (France) are presented. The emission scenario is represented by an ethanol pool fire. Primary emissions are determined by the combustion chemical kinetics. Subsequent decays in the composition of the emissions are determined by appropriate atmospheric chemistry models. Dispersion simulations are performed for representative diurnal / nocturnal and seasonal atmospheric conditions. The mesoscale solver WRF (Weather Research and Forecasting Model) is used to obtain atmospheric conditions. QUIC dispersion modelling system is used for determining the flow field over the considered area and the simulations of the atmospheric dispersion. The results obtained concern the hazardous material atmospheric concentrations over the considered area.
