Streszczenie:

The article presents the modeling of the dynamics of the vapor-gas mixture and heat and
mass transfer (sorption-desorption) in the capillary structure of the porous medium. This approach is
underpinned by the fact that the porous structure is represented by a system of linear microchannels
oriented along the axes of a three-dimensional coordinate system. The equivalent diameter of these
channels corresponds to the average pore diameter, and the ratio of the total pore volume to the
volume of the entire porous material corresponds to its porosity. The entire channel area is modeled
by a set of cubic elements with a certain humidity, moisture content, pressure and temperature.
A simulation is carried out taking into account the difference in temperatures of each of the phases:
solid, liquid and gas.
