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.

优化天线形鳍片配置以增强辐射传热三重热能储存系统的凝固效果

本研究的目的是通过在三联管储能装置中加入混合纳米粒子（MoS2-Fe3O4）和利用独特的优化天线形鳍片配置，提高潜热储能系统（LTESS）中相变材料（PCM）的凝固速率。通过应用有限元法（FEM），并考虑一些数值分析，解决了这一问题。为了研究具有辐射参数的天线形翅片在凝固过程中的各种角度和尺寸的影响，开发了一个通过历史实验数据验证的计算模型。本文将分析不同角度和尺寸的天线形翅片与辐射参数在凝固过程中的影响。结果表明，与零辐射相比，当 Rd = 1 时，全凝固时间（FTS）减少了 51%，表明凝固过程的效率显著提高。此外，在 4000 秒时，Rd = 0 和 Rd = 1 的平均温度不同，明显下降了 4.51°。此外，利用田口和响应面方法 (RSM)，确定了最佳设置，以最大限度地缩短三联管 LHESS 的全部凝固时间。有趣的是，还为 FST 建立了高度准确和精确的相关性。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
