• The distribution of a air pollutant which is emitted from the building materials in a room can be quantitatively predicted by the CFD (Computational Fluid Dynamics) technique. The authors develop a CFD analysis incorporating a pollutant sorption model which allows the detailed analysis of the effect of reducing the concentration of the indoor air pollutant through the sorption on walls and other interior surfaces. In order to demonstrate the usefulness of the CFD analysis incorporating the sorption model, we conduct an analysis of concentration distribution for an indoor air pollutant in a closed heated room. We examine the effect of reducing the concentration of the indoor air pollutant by installing an adsorber in the walls and ceiling, assuming that the pollutant was emitted from the floor of the room. The sorption model incorporated is very simple and assumes zero concentration at the adsorbing surfaces. The CFD analysis shows the significant effect of reducing the concentration of the indoor air pollutant by the absorbing surfaces.
