“…The ratio was found to determine the dimensionless vapor density, the vapor pressure at an arbitrary point z of the wood plate during the drying process [17,20]. An equation was obtained to determine change in relative moisture content over time and the equation of motion of the phase boundary of the dried and moist zones…”

The article deals with constructing and implementing mathematical models of non-isothermal moisture transfer during drying of anisotropic capillary-porous materials, in particular wood, taking into account the movement of the evaporation zone for non-steady drying schedules, as well as to the development of effective analytical and numerical methods for their implementation. An analytical-numerical method for the determination of non-isothermal moisture transfer under non-steady schedules of the drying process has been developed, taking into account the dynamics of the phase transition boundary change. Calculation relationships are established for determining the phase transition temperature taking into account transport gradients and time for which the relative saturation reaches the boundaries of the phase transition.
