N2 - Thermal energy storage systems (TESS) are increasingly recognized as a solution to the global energy crisis, offering a means to balance energy supply and demand. While, phase change materials (PCMs), are vital components of TESS that can store and release large amounts of energy during their phase transition process. However, their low thermal conductivity limits melting performance, posing a significant challenge. This study addresses this issue by incorporating nanoparticles and novel arc fins with a minimal fin volume fraction to enhance TESS performance. Numerous studies investigate the arc fins are more effective and give better performance. But in this current investigation, we used unique geometric features such as eccentric arc fins (CAF) and concentric arc fins (EAF) with conventional fins to improve the melting performance. Two different type of nanoparticles namely aluminium oxide (Al2O3) and multi-wall carbon nano-tubes (MWCNTs) are dispersed in molten salt (PCM) for this investigation. The results indicate that the melting performance improve by using the combination of novel fins and nano particles. Melting time for case 1–5 reduced 87.03 % compare with case 1.0.
