An experimental study of dynamic solid-liquid phase equilibrium in the pores of a porous medium

摘要

An experimental study has verified the dynamic equation of state which is derived from a thermodynamic model representing simultaneous heat and mass transfer from the water 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) enables us to show experimentally the relationship between temperature, pore lquid pressure and solid pressure at the interface, and liquid supply pressure.
