In these equations the volume fractions of each phase, the potentials, such as, the temperature, pressure and concentration, and the corresponding fluxes, are permitted to jump in value across the phase-change interfaces. As an example of application of the derived continuum model, we specialize the theory to the problem of propagation of melting/freezing interfaces in a salt-water saturated porous medium for a coupled process governed by heat flow, fluid flow and species transport UR - https://www.sciencedirect.com/science/article/pii/0017931089900112 ER -
