Solid–Liquid Phase Change
Besides the classical ice–water phase change, the solid–liquid phase change exhibits many different behaviours: diffuse with respect to time and space phase change, phase change with voids and bubbles, phase change with different densities, dissipative phase change, irreversible phase change, phase change with thermal memory,... The different predictive theories result from the choices of the free energies and pseudopotentials of dissipation. Examples are given: soil freezing and the insulation of an house in winter, liquid gas underground storage, fossil permafrost.
