A dynamic equation of state at the solid-liquid interface for a liquid-saturated "solid-liquid porous media" system has been derived from a thermodynamic study modeling simultaneous heat and mass transfer through porous media from the liquid supply front to the solid-liquid interface, as the very first step in building a mathematical model which may macroscopically describe a freezing expansion phenomenon with mass transfer in saturated porous media. It has been revealed that the derived dynamic equation of state generalizes the so-called generalized Clausius-Clapeyron equation, i.e. the static equation of state for porous media without mass transfer, and that mechanical energy produced at the solid-liquid interface is equal to mechanical energy dissipation due to the mass transfer.
