| Summary: | A numerical investigation on melting of Phase Change Material (PCM) after dispersed with various types of nanoparticles is presented in this study. Nanoparticles with high thermal conductivity properties could be a good additive to enhance the thermal performance of PCM in latent heat thermal energy storage. This paper focus on the melting rate of paraffin wax as PCM dispersed with three types of nanoparticles: Alumina (Al 2 O 3 ), Copper oxide (CuO) and Zinc Oxide (ZnO) in a 25mm ×25mm square enclosure. The effect of heating side of the wall and the concentration of nanoparticles dispersed in PCM were investigated. ANSYS Workbench 17.0 that included mesh generation tools and FLUENT software was used to run the simulation. Enthalpy porosity method was applied in this numerical study. Results shown that heat transfer rate was improved by adding low volume fraction of nanoparticles. Heating from the side wall of the enclose has better melting rate than heating from below. |
