Abstract

This study investigates a hybrid Phase Change Material system for enhanced thermal energy storage in refrigerated transportation, bridging gaps in Latent Thermal Energy Storage applications. A dual phase change material configuration of RT27 and n-octadecane, integrated with liquid cooling and cooling pipe fins, is analyzed using Computational Fluid Dynamics simulations. The study optimizes thermal management in refrigerated trucks by varying the number of fins. Key performance indicators include temperature distribution, liquid fraction, and melt fraction reduction. Results show that the hybrid system with eight fins achieves a 6.55 % reduction in peak temperature for n-octadecane compared to the base case. The melting fraction of RT27 is reduced by 26.51 %, and n-octadecane melting is reduced by 71.93 % with eight fins. Machine learning models, specifically Levenberg-Marquardt algorithm and Scaled Conjugate Gradient, predict melt fractions with high accuracy, with R-values of 0.933 and 0.941, respectively, for the base case. The findings highlight the effectiveness of hybrid cooling systems, demonstrating significant improvements in thermal energy storage and refrigeration performance.

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.
