摘要：

In current simulation, Galerkin approach was employed to achieve the best design of heat storage. Utilizing nanoparticles as well as mounting fins were promising ways to improve the efficiency of unit. The unsteady discharge process was analyzed in various time steps and outcomes were reported as contours, profiles and solid front. Acceleration in discharging means that more uniform process and better performance. Increasing the fin length is effective way to achieve greater discharging rate. Outcomes revealed that greater size of nanoparticles yielding higher performance when d(p) < 40 nm. (C) 2019 Elsevier B.V. All rights reserved.
