Experimental comparison of longitudinal and annular fins using PCM for Thermal energy storage

This work deals with comparative study of longitudinal and annular fin using PCM in a thermal energy storage unit experimentally and numerically. The TSU under analysis Consists of paraffin wax as PCM with melting Temperature of 55°C to 60°C. Liquid heat transfer fluid passes between the tubes to charge and discharge the storage unit. Thermal storage tank is connected to the experimental setup which consists of hot and cold-water tanks and experiment is carried our initially charging and discharging by Longitudinal fin process by passing heat transfer fluid similarly the charging and discharging by Annular Fin process by passing heat transfer. The experimental results show that usage of Longitudinal fin and Annular fin for charging and discharging has different heat transfer rate. Even efficiency is increased around 6% for the longitudinal finned heat exchanger than the Annular finned heat exchanger.
