“…Though, the criteria for the choice of a PCM for a specific application is its melting temperature, but other properties such as the latent heat of fusion, thermal conductivity, thermal stability, density, and lower volume change, also play significant role and therefore are essential to be considered [5,6]. Authors in [7] presented a detailed numerical investigation of a heat storage system's inclination effect on the PCM melting process in order to comprehend the natural convection mechanism inside a shell and tube Thermal Energy Storage (TES) unit. Several unit positions were examined to interpret physically the thermal demeanor of the fusion process in terms of heat transfer modes estimation, PCM melting rate, and axial and radial temperatures distribution.…”

The intermittent nature of renewable energy sources such as solar and wind necessitates integration with energy-storage units to enable realistic applications. In this study, thermal performance enhancement of the finned Cylindrical Thermal Energy Storage (C-TES) with nano-enhanced Phase Change Material (PCM) integrated with the water heating system under Storage, Charging and Discharging (SCD) conditions were investigated experimentally. The effects of the addition of copper oxide (CuO) and aluminum oxide (Al2O3) nanoparticles in PCM on thermal conductivity, specific heat, and on charging and discharging performance rates were theoretically and experimentally investigated and studied in detail. The experimental apparatus utilized paraffin wax as PCM, which was filled in Finned C-TES to conduct the experiments. The experimental results showed a positive improvement compared with the non-nano additive PCM. The significance and originality of this project lies within the evaluation and identification of preferable metal-oxides with higher potential for improving thermal performance.
