Abstract

This paper presents a solution to the entalpy equation corresponding to solid-liquid phase change systems by the dual reciprocity boundary element method. The physical model is based on the one-phase averaged formulation of incompressible distinct or continuous phase-change mate- rials with temperature-dependent thermal conductivities and specific heats of the solid and liquid phases. The boundary-domain integral equation is structured by Green's function of the Laplace equation and by the dual reciprocity boundary representation of the domain integrals. Discretization in a two-dimensional cartesian frame is based on straight line boundary elements with constant space and linear time shape functions, and on glob
