Removal of contaminants released from room surfaces by displacement and mixing ventilation : modeling and validation

Experimental measurements and CFD simulations were carried out to study the contaminant dispersion in a ventilated room with an area source release. A displacement ventilation system and three mixing ventilation systems using a grille, square, and slot diffuser were used. A model was validated to study the effects of airflow and the area source location on the dispersion of the contaminants. The simulation results have been compared to the experimental data, the conclusion are presented.
