An experimental study has verified the dynamic equation of state derived from a thermodynamic model representing simultaneous heat and mass transfer from the lipuid supply front to the solid-liquid interface in a liquid saturated porous medium. Measurement of pore liquid pressure at the solid-liquid interface fixed on the top surface of an Ohya-tuff specimen(the porous medium)enabled us to experimentally verify the relationship between temperature, pore liquid pressure and solid pressure at the interface, and liquid supply pressure. This experimental method was established by re-verifying the so-called Clausius-Clapeyron equation(GCCE), the static equation for a porous medium without liquid flow. This study also clarified the relationship between the dynamic equation of state and the GCCE on the pore liquid pressure-liquid supply pressure plane.
