Numerical Simulation and Optimization of a Phase-Change Energy Storage Box in a Modular Mobile Thermal Energy Supply System

Featuring phase-change energy storage, a mobile thermal supply system (M-TES) demonstrates remarkable waste heat transfer capabilities across various spatial scales and temporal durations, thereby effectively optimizing the localized distribution structure—a pivotal contribution to attainment of objectives such as “carbon peak” neutral”. To heighten efficiency for heating, this research introduces innovative concept modular storage transportation. This is brought life through development meticulously designed compartment system. Employing computational fluid dynamics (CFD), an in-depth exploration into performance M-TES container adapted material (PCM) conducted. By implementing fin arrangements on inner wall module, upsurge in liquid phase-transition rate achieved comparison design lacking fins—this improvement approximating around 30%. However, it essential acknowledge that augmentation gradually recedes with proliferation fins or escalation their height. Moreover, integration expanded graphite erythritol emerges profoundly effective amplifying conductivity PCM. Notably, addition 15.2% volume fraction erythritol, duration experiences drastic reduction nearly 10% its original duration, signifying momentous advancement performance.
