ABSTRACT Energy and the environment are essential issues worldwide. Sustainable design of energy systems plays a key role in enhancing thermal efficiency and reducing environmental emissions. This study uses COMSOL Multiphysics 6.2 to investigate the impact of 12 extra fin configurations on the thermal effectiveness of a tube‐in‐tube heat exchanger with annular fins used as a thermal energy storage system. This system is a tube‐in‐tube heat exchanger with a total height of 400 mm and a 44 mm diameter. Paraffin RT‐35 is used as a storage medium. The objective of this study is to determine the optimal configuration that minimizes material consumption in the production of fins while simultaneously enhancing the energy storage efficiency of the energy storage unit. The findings indicate that the majority of the proposed scenarios in this study demonstrate a significant effect on both the charging (melting) and discharging (solidification) duration. The optimal configuration improved the melting stage temperature by 3.95%, reduced full melting time by 33.88%, and decreased solidification time by 1.31%. Taking into account the energy implications and material efficiency, the novel design of this thermal energy storage system significantly demonstrates a reduction in material consumption and melting duration by 16.67% and 10.88%, respectively. In conclusion, adopting the proposed design approach enhances the thermal efficiency and sustainability of the energy systems.
