Abstract

Many studies using computational fluid dynamics (CFD) analysis have been performed on the concentration distribution of indoor contaminants generated in building materials. This study was an attempt to quantitatively evaluate the effect of the contaminant emission source on the concentration and breathing quantity in a human breathing area using the contribution ratio of pollution (CRP) along with CFD analysis. The modeled human body is placed lying and sitting in a room. It is ventilated with natural infiltration. We applied these concepts to the more realistic case of inhalation by a human occupant in a room with three dimensional CFD, assuming the human mouth at inhalation to be an exhaust opening. As a result, the contaminant that was emitted from the floor had a significant influence on the breathing quantity of the contaminant. CFD analysis also indicate that the quality of the breathing air depends on the flow field around a human body.
