A Phase Change Problem including Space-Dependent Latent Heat and Periodic Heat Flux

Abstract

In this paper, a mathematical model related to a problem of phase-change process with periodic surface heat flux and space-dependent latent heat is considered. We have used the homotopy analysis approach to acquire the solution to the problem. To show the correctness of the calculated result, the comparisons have been discussed with the existing exact solution in a particular case. The effect of various parameters on the movement of the interface is also investigated. © 2019 In for Math Publishing Group.
