Energy storage simulation involving NEPCM solidification in appearance of fins

In this paper, to demonstrate the behavior of NEPCM during discharging within a triplex tank, numerical approach has been utilized. Reduction of entropy generation due to adding nanoparticle can help to get better performance of unit. Outcomes reveal that temperature declines with adding nanoparticles while needed time for solidification reduces. Reduction of solidification time with rise of fin length is associated with enhance of conductivity of new fluid. Lower length of fin prolongs the solidification owing to reduction of conduction. Augmenting dp is more helpful if it value is lower than 40 nm
