Abstract
The objective of this study is to enhance the rate of solidification of Phase Change Materials (PCMs) in Latent Thermal Energy Storage Systems (LTESSs) by incorporating hybrid nanoparticles (MoS2-Fe3O4) and utilizing a unique optimized antenna-shaped fin configuration in a triplex-tube energy storage device. The problem was solved by applying the Finite Element Method (FEM), considering some numerical analysis. For studying the effects of a variety of angles and dimensions of antenna-shaped fins with a radiation parameter during the process of solidification, a computational model validated by historical experimental data is developed. This paper will present an analysis of the effect of different angles and dimensions of antenna-shaped fins in conjunction with the radiation parameter during the solidification process. Results show that the full solidification time (FTS) decreases by 51 % when Rd = 1 compared to zero radiation, indicating a significant improvement in the efficiency of the solidification process. Furthermore, at 4000 s, the average temperatures for Rd = 0 and Rd = 1 differ, showing a noticeable drop of 4.51°. Furthermore, using Taguchi and Response Surface Methodology (RSM), the optimal settings were determined to minimize the full solidification time in the triplex-tube LHESS. Interestingly, a highly accurate and precise correlation for FST was established.
