摘要

Discover the superior potential of latent thermal energy storage over sensible energy storage due to its higher capacity and temperature stability during heat transfer. This research presents a validated numerical model to analyze the melting, temperature and velocity profiles of external fins in an annular duplet tube heat exchanger (DTHX) with and without a Y-configuration for phase change materials (PCMs) by comparing Y-configuration to the standard. Utilizing ANSYS Fluent simulation, the model’s accuracy is confirmed against literature data. Results reveal Y-configuration’s significant impact on total melting time and buoyancy reduction by 50%. This validated model holds promise for optimizing configurations and probing diverse PCM heat transfer aspects, encompassing conduction, convection, and buoyancy-driven effects.
