Non-Equilibrium Thermodynamics of Phase-Transitions

TLDR: The boundary between two phases of a one-component system contains two scalar force-flux pairs as discussed by the authors, i.e., the jumps of the temperature and of (essentially) the chemical potential at the interface; these jumps vanish if the four coefficients vanish.

Abstract: Abstract The entropy production - (3.8.) - in the boundary between two phases of a one-component system contains two scalar force-flux pairs. The \"forces\" are the jumps of the temperature and of (essentially) the chemical potential at the interface; the \"fluxes\" are the heat and mass fluxes nor-mal to the interface. So, four phenomenological coefficients appear in the pertaining local linear constitutive laws - (4.14 and 15) - for the boundary conditions. They can in principle be de-termined by a stationary heat conduction and phase transition experiment. Only measurements of temperature jumps - (5.14 and 15) - are involved. These jumps vanish if the four coefficients vanish
