Abstract: This study focuses on the heat transfer intensification of concentric tube type thermal energy storage (TES). The collective influence of aspect ratio (ratio of length to diameter of the tube) and number of fins is investigated. To optimize thermal energy storage, first an optimal aspect ratio investigated. And then, optimal number of fins is obtained. Results are compared based on the amount of liquid fraction available after 120 minutes of charging and discharging. It was found that with an increasing aspect ratio, liquid fraction also increased, but up to the aspect ratio of 11. Afterwards, an increased aspect ratio showed insignificant change in the liquid fraction. Similarly, liquid fraction in case of charging was increased with increasing the number of fins up to 8. Afterward, an increased number of fins showed insignificant change in the liquid fraction.
