Simulation study of volatile organic compounds emission from multi-layer building materials

摘要

This paper reports a simple mathematical model which considers both the diffusion within three layer building materials and the mass transfer resistance through the air boundary layer to predict the emission of volatile organic compounds from threelayer building materials. A general solution method based on Laplace transform is presented. Compared to other models capable of accounting for emissions of volatile organic compounds from multi layer building materials, the present model is fully analytical instead of being numerical. The present model was validated by the experimental data from the specially designed test. The results indicated that there was a good agreement between the model predictions and the experimental data.
