MODELING OF HEAT AND MASS TRANSFER
IN CAPILLARY-POROUS MATERIALS

A system of differential equations for heat and mass transfer in
capillary-porous materials in a hydroscopic moisture-content field
is derived with allowance for kinetics of moisture desorption,
two-phase filtration, and liquid pressure determined by the action
of surface forces. An analysis is made of the results of
a computational experiment illustrating evolution of the moisture
content, temperature, and vapor pressure fields against the
material characteristics and kinetic coefficient.
