A CFD results-based reduced-order model for latent heat thermal energy storage systems with macro-encapsulated PCM
König Haagen, Andreas; Faden, Moritz; Diarce Belloso, Gonzalo (Elsevier, 2023-12)Macro-encapsulation of phase change material (PCM) is a promising approach to overcome a serious drawback of many latent heat thermal energy storage systems (LHTESSs): their low thermal power. Simulations are often used ... -
A comprehensive study of the phase segregation of a urea-based phase change material tested under thermal cycling conditions
Quant Colón, Laura Marcela; Diarce Belloso, Gonzalo; Bouzas Vila, Lourdes; García Romero, Ane Miren (Elsevier, 2023-04)Eutectic mixtures are used as PCMs due to the possibility to tailor the melting temperatures and mainly because the phase transition occurs at a unique temperature. Eutectic mixtures are assumed to be congruent melting and ... -
Comparative study on bubbling and shearing techniques for the crystallization of xylitol in TES systems
Navarro, Miguel; Diarce Belloso, Gonzalo; Lázaro, Ana; Rojo Hurtado, Ander; Delgado, Mónica (Elsevier, 2023-03)Xylitol is a promising phase change material for thermal energy storage at low and medium temperatures, but its supercooling and low crystallization rate can hinder its performance in actual systems.
