Analysis on the heat storage unit through a Y-shaped fin for solidification of NEPCM

The primary goal of current research is the expedition of the discharging process with the use of Al2O3-nanoparticles and Y-shaped fins. The nanoparticle can be dispersed in a PCM to eliminate the limitations of them. Newton-Raphson scheme with a combination of Finite element method were implemented to discuss the novel outcomes of the present analysis. A powerful numerical approach is involved in simulating time-dependent phenomena in a complex geometry. Outcomes prove that dispersing nanoparticles is a good way of enhancing the discharge rate. As the radius of nanoparticle augments up to 20 nm, total energy decreases and profile has been converged in lower time. A comparison reveals that the outputs have excellent agreement with the experimental results. •Heat storage unit with Y shaped fins for solidification of NEPCM was examined.•Galerkin FEM was applied to determine the numerical outcomes.•Dispersing nanoparticles is beneficial way for augmenting discharge rate.•An excellent graphical comparison was present to validate the current results.
