Abstract

A model for the description of the heat and moisture transfer in a porous material is proposed. The density of the saturated vapor and the transfer coefficients of the liquid and vapor moistures depend on the temperature. At the same time, the conductivity coefficient of the porous material depends on the moisture. On the basis of the proposed model, a numerical simulation of the heat and moisture transfer for a drying process has been performed.
