Predicting gaseous pollutant dispersion around a workplace

This study presents a prediction of the space-time evolution of airborne pollutant dispersion following the accidental rupture of a containment enclosure (fume cupboard, glove box, pressurized gas duct etc.). Gas tracing experiments have been carried out along with multidimensional simulations using CFD tools. Comparisons between experimental and numerical results largely agree. Then a model was built, easy to use in safety evaluations of radioactive material containment, for radiological protection inside nuclear facilities and for the evaluation of toxic gaseous compounds in the chemical industry.
