Abstract: Intermittency in solar energy, in the case of thermal applications, it is necessary to store this energy in the form of thermal energy. It can be used when solar energy is unavailable and thus helps in minimizing the mismatch between energy demand and supply. 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. Moreover, suitable working parameters for the best performance of this thermal storage system are also obtained. 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. Better performances were observed at a higher value of inlet temperature and mass flow rate of HTF. Moreover, suitable working parameters for the best performance of this thermal storage system are also obtained.
