MODELING THE VOC EMISSIONS OF SOLID/WET BUILDING MATERIAL ASSEMBLY AND ITS ASSESSMENT

摘要

This paper presents the theoretical investigation of the VOC emissions from the solid/wet material assembly. A mass transfer model was developed considering the diffusion and sorption within the solid, and the convection (i.e., airflow) over the solid material. The wet material was modeled as an emission source with a constant decay rate and a negligible thickness. The analytical solution was obtained using the integral transform technique. This proposed model was assessed by comparing its prediction to small-scaled chamber test data of carpet/adhesive assembly in the literature. The effect of air velocity (i.e., Reynolds number) on the emission of the assembly was studied. The emission rate increases as the air velocity increases; however, the effect of air velocity depends on the solid material properties.
