A numerical method for phase-change problems [PDF]
International Journal of Heat and Mass Transfer, 1990 A highly accurate and efficient finite-difference method for phase-change problems with multiple moving boundaries of irregular shape is developed by employing a coordinate transformation that immobilizes moving boundaries and preserves the conservative forms of the original governing equations.

A Series Solution for Heat Conduction Problem with Phase Change in a Finite Slab
Abstract and Applied Analysis, 2014 A two-dimensional differential transform method is applied to solve one-dimensional phase change problems in a slab of finite thickness, which is subjected to convective thermal loading at one surface and a constant prescribed temperature at the other ...

Explicit solutions to phase change problems [PDF]
Quarterly of Applied Mathematics, 1983 We examine two heat transfer and phase change problems having explicit solutions. The first involves melting of an initially cold material and clarifies the meaning of a recent result of Tarzia [5]. The second concerns a model of binary alloy solidification which, in some cases, is seen to be incorrect.

An Accurate Approximation of the Two-Phase Stefan Problem with Coefficient Smoothing
Mathematics, 2020 In this work, we consider the heat transfer problems with phase change. The mathematical model is described through a two-phase Stefan problem and defined in the whole domain that contains frozen and thawed subdomains.

On the one-phase reduction of the Stefan problem with a variable phase change temperature [PDF]
, 2015 The one-phase reduction of the Stefan problem, where the phase change temperature is a variable, is analysed. It is shown that problems encountered in previous analyses may be traced back to an incorrectly formulated Stefan condition.
