Applications of the Clapeyron Equation to Water and Ice in Porous Media

The equilibrium condition for water and ice in an air-free porous medium is presented. The equation of state for this system is the Clapeyron equation. This equation is presented in a general form that explicitly shows the pressure-difference dependence with temperature for water and ice. Five solut...

Description
Summary:The equilibrium condition for water and ice in an air-free porous medium is presented. The equation of state for this system is the Clapeyron equation. This equation is presented in a general form that explicitly shows the pressure-difference dependence with temperature for water and ice. Five solution scenarios are then discussed in terms of applicability to porous media. (AN)
