A Mass Transfer Model for Simulating VOC Emissions from Building Materials

Abstract

Based on heat and mass transfer hypothesis and existing theoretical models, a mathematical ideal for volatile organic compounds (VOC) emission was established to estimate the evolution of pollutant concentration inside wet building materials. The dynamic distribution characteristics of VOC concentration with multi-pollution sources in an actual building were simulated. The results show that the specific distribution form of indoor VOC concentration is related to its own density and the arrangement of obstacles. It will significantly promote/inhibit VOC emission from indoor building materials.
