Analytical modelling of transient phase-change problems
International Journal of Energy Research, 2000 In this paper, an analytical solution for the temporal location of moving solid–liquid interface of a phase-change process, occurring in parallel plate channels, is presented. The motion of the solid–liquid interface is governed by the convection from the surface of one of the plates, while constant heat supply is assumed to occur on the surface of the

Numerical methods in phase-change problems [PDF]
Archives of Computational Methods in Engineering, 1994 This paper summarizes the state of the art of the numerical solution of phase-change problems. After describing the governing equations, a review of the existing methods is presented. The emphasis is put mainly on fixed domain techniques, but a brief description of the main front-tracking methods is included.

Symplectic reduction and the problem of time in nonrelativistic mechanics [PDF]
, 2010 Symplectic reduction is a formal process through which degeneracy within the mathematical representations of physical systems displaying gauge symmetry can be controlled via the construction of a reduced phase space. Typically such reduced spaces provide

An Optimum Enthalpy Approach for Melting and Solidification with Volume Change
Energies, 2019 Classical numerical methods for solving solid–liquid phase change assume a constant density upon melting or solidification and are not efficient when applied to phase change with volume expansion or shrinkage.
