Abstract: Paraffin is an excellent phase change material (PCM) for latent heat storage, but it does not efficiently use stored energy because of its low thermal conductivity. In this study, nickel and copper foams were added to paraffin to enhance heat transfer. A Hot Disk Thermal Constants Analyzer measured the thermal conductivity of the paraffin composites using the transient plane source (TPS) method. The addition of copper foam enhanced the thermal conductivity of paraffin by 15 times, and nickel tripled the thermal conductivity. These results can help improve the energy efficiency of latent thermal energy storage (LTES) systems in the future.
