RT Journal Article ID 6be7d6f2021c84f7 A1 Petrone, Giuseppe A1 Cammarata, Giuliano T1 NUMERICAL SIMULATION OF PHASE CHANGE MATERIALS MELTING PROCESS JF Computational Thermal Sciences: An International Journal JO CTS YR 2013 FD 2013-04-23 VO 5 IS 3 SP 227 OP 237 K1 phase change K1 rectangular enclosure K1 enthalpy method K1 natural convection AB This study deals with a numerical investigation on the melting process of a phase change material (PCM) in a differentially heated rectangular enclosure. A finite-element-based software is used in order to solve Navier–Stokes and energy equations in the considered system. Adopting the enthalpy formulation, one single equation is used to solve transient conduction and convection heat transfer in both the solid and liquid phase. The liquid flow patterns during the melting process have been captured and the instantaneous marching of the liquid–solid interface is presented. In addition, the temperature distributions in the PCM are reported. A successful comparison between obtained numerical results with experimental ones found in the literature is presented.
