Phase Change Materials (PCMs) show significant potential for thermal energy storage. PCMs are essentially materials that can absorb and release a significant amount of energy during a phase transition, thanks to their high latent heat, within a specific temperature range. However, due to their low thermal conductivity, it becomes necessary to employ heat transfer enhancement techniques in order to expedite heat accumulation, including convection effects and the study of melting regimes. This thesis explores the incorporation of metal foam into a PCM to enhance its heat transfer capabilities. Initially, a theoretical model for a metal foam/PCM composite is presented. Subsequently, a scale analysis on experimental tests is conducted using Paraffin wax placed within aluminum foams of varying porosity and pore size.
