Abstract: Nowadays, research is conducted to focus on developing efficient and cost-effective energy storage systems. Sensible and latent heat thermal storage systems are the most widely used energy storage technologies. Latent thermal storage is more advantageous than sensible thermal storage as it has higher energy storage density with isothermal charging and discharging process. However, it has poor heat transfer characteristics resulting in more charging and discharging times. To address this issue, various methodologies related to heat transfer enhancement have been suggested. The main objective of this work is to enhance the heat transfer of the thermal storage system by the inclusion of longitudinal fin configuration. The thermal storage system considered is vertical shell and tube type, where paraffin wax is used as phase change material (PCM), and water is used as heat transfer fluid (HTF). The performance of a shell and tube type latent storage system with and without fins has been experimentally investigated under different operating conditions. The operating parameters are considered as the inlet temperature of HTF. The results obtained under the present study revealed that additions of longitudinal fins improve the system efficiency significantly by reducing the charging and discharging times.
