Abstract


The numerical research of the suggested phenomenological model of heat and moisture transfer in a porous material is performed. The model is described by a system of equations of four unknown functions - the water concentration wl, water vapor concentration wv, temperature T and source I as functions of the space variable x and time variable t. Different cases of initial and boundary conditions are considered that correspond drying of a wet sample or wetting of a dry sample. Calculation results show that during the drying process of a wet sample the temperature of the sample decreases under an initial, room temperature and during the wetting process of a dry sample or the temperature is not changing or the heat in the sample is increasing depending on that whether a water or a hot water vapor is supplied to the boundary.
