In this research work, investigation of the impact of Phase Change Material concentration, thermal conditions surrounding the Thermal Energy Storage System for the charging and discharging process was conducted by including Al2O3 as nano-material with a varying concentration – 0% (Base Model), 1% (Variant-1), 2% (Variant-2) and 3% (Variant-3). Three thermal conditions surrounding the TESS were studied – complete insulation (Configuration A), atmospheric condition on one side (Configuration B), partial exposure (Configuration C). These were studied using experimental and CFD methods for two heat loads 125 W and 175 W. Transient, 3-Dimensional, Laminar CFD simulations were conducted using ANSYS FLUENT with the Enthalpy-Porosity approach. For Configuration A under the heat load of 125 W, Variant-1 had high temperature at the monitoring-point followed up by the Variant-2. When the environmental conditions were imposed on the opposing wall of the heat supply (Configuration B) of 125 W, the melting inside the TESS monitoring-point had occurred at 24 minute for the Variant-1. For the Configuration C under 175 W, the peak temperature of 400 K was observed for the Variant-1. When the heat supply was increased to 175 W from 125 W for the Configuration A, the melting initiation at the monitoring-point had occurred faster. Overall, the inclusion of nano-materials with the PCMs had resulted in this thermal advantage.
