Numerical simulation of a latent heat thermal energy storage system with enhanced heat conduction
TL;DR: In this article, the thermal performance of a latent heat storage system with and without fins has been analyzed using an enthalpy formation and a fully implicit finite difference method, and the magnitude of the melt fraction with fins is found to be considerable, dominating the melting fraction when no fin is used.

A fixed grid numerical modelling methodology for convection-diffusion mushy region phase-change problems
Vaughan R Voller,C. Prakash +1 more
TL;DR: In this article, an enthalpy formulation based fixed grid methodology is developed for the numerical solution of convection-diffusion controlled mushy region phase-change problems, where the basic feature of the proposed method lies in the representation of the latent heat of evolution, and of the flow in the solid-liquid mushy zone, by suitably chosen sources.

Free and moving boundary problems
TL;DR: In this paper, a front-tracking method is used to solve moving boundary problems and an analytical solution of seepage problems is proposed. But this method is not suitable for solving free boundary problems.
