To clarify the effect of their geometries on the formaldehyde emission rate from building materials, we established a numerical model and analysis method for quantitatively investigating the formation of transient formaldehyde concentration distribution in small, airtight, glass desiccators. The detailed geometries of the desiccators, formaldehyde emission materials and the adsorbent were reproduced as 3D digital models. Numerical analyses were carried out to investigate transient formaldehyde emissions, molecular diffusion, and sorption. We considered the effect of adsorbent evaporation based on a three-component gas mixture theory. The results of the numerical analyses confirmed the impact of the adsorption and diffusion resistance of the water surface on the measured formaldehyde emission rates.
