For centuries, statics and dynamics of two-phase heterogeneous systems were and remain to be in the focus of multiple academic and engineering disciplines. Phase transformations phenomena include both strong reversible and irreversible effects. Many of the irreversible effects, such as friction, viscosity, heat conduction, etc., are the same as in the single-phase systems. In addition to those, the two-phase systems are known for one more irreversible effect. It is the effect entailed by finite rate of kinetics of phase transformation. Below, we explore this irreversible phenomenon for two two-phase heterogeneous systems: (i) the layered system of incompressible phases in the external gravity field and (ii) the two-phase, two-layered self-gravitating planet.
