Abstract

Abstract: The rate of discharging has been investigated in this article, involving various shapes of additives. The numerical method for analyzing such transient phenomena has been selected with selecting implicit technique for unsteady terms. The fraction of additives is lower than 0.05 which means that selecting a single phase model is logical. The nanoparticles have been added to enhance the speed of the process. The model includes two equations and solutions were achieved by utilizing the Galerkin approach. New styles of geometry involving fins were applied. The freezing increases as nanoparticles were added into base material. The period of process declines with growth of ϕ from 303.74 s to 222.37 s. The period of process for m = 8.6 is 1.075 times bigger than that of m = 4.8. Highlights: Discharging was investigated, involving various shapes of additives. The period of process for m = 8.6 is 1.075 times bigger than that of m = 4.8. The period of process declines with growth of ϕ from 303.74 s to 222.37 s.
