Résumé

The research studies the effects of source type and location on contaminant dispersion and exposure in a displacement ventilated room. A full-scale environmental chamber is used to measure the airflow and contaminant distributions in a mockup office setting. A point source is positioned at four different locations to examine the sensitivity of the contaminant distribution to source locations. This is followed by the exposure measurements in the same room with an area of contaminant sources on the floor. Experimental data are used to validate a computational fluid dynamics (CFD) model, and the CFD program is further applied to simulate the contaminant dispersion with more area sources.
