The finite element analysis of water vapor diffusion in a brick with vertical holes

摘要

This paper presents a finite element analysis of water vapor diffusion in a brick with vertical holes. The isotherms, isodensity, isopressure and isohumidity surfaces considering the longitudinal and transverse direction diffusion of water vapor in a brick with vertical holes are determined. The numerical results obtained from this study are usually used in the engineering practice to optimal design the spatial structure of building walls. The results obtained from this analysis are compared with the experimental data taken from the literature, and a good agreement is observed.
