Solidification process through a solar energy storage enclosure using various sizes of Al2O3 nanoparticles

In this article, different shapes of aluminum oxide nanoparticles have been dispersed in to pure H2O to expedite discharging rate in existence of thermal radiation. Galerkin Finite element method is the best tools for time dependent phenomena in a complex geometry such as current enclosure. To calculate nanofluid properties, previous experimental correlations have been employed. Outputs prove that dispersing nanoparticles can expedite the discharging process. Size of nanoparticles has optimum value in which maximum performance can be observed. Considering radiation term can enhance the discharging rate. Impact of amplitude of inner cylinder is more effective in presence of thermal radiation.
