Internationally, energy-storage technologies have facilitated the large-scale utilization of renewable energy, reducing reliance on conventional power generation and enhancing energy efficiency. In pursuit strengthening efficiency phase-change systems, focus lies further vertical shell-and-tube systems. This study investigates influence two different heat-transfer fluid (HTF) injection directions melting materials (PCM) in a latent heat storage (LHS) system. The behavior PCM is analyzed under both pure conduction natural convection conditions. research findings reveal that during initial stage, HTF methods primarily rely thermal conduction, resulting no significant changes melting. However, later stages convection, bottom exhibits superior compared to top injection. Under constant volume material, pipe length thickness affect process. As increases within range 1.6 m 0.2 m, time also increases. results show reduced by almost 15,000 s when tube H exceeds 800 mm, regardless whether injected at or bottom. this paper, we obtained three composites containing 10% expanded graphite save 5.3%, 10.2%, 14.3% time, respectively, paraffin = 200 mm are considered. For injection, saved 7.7%, 12.5%, 17.2% respectively. emphasizes more effect priming improving time.

The Canadian Journal of Chemical Engineering, Journal Year: 2024, Volume and Issue: 102(11), P. 3852 - 3866

Published: June 24, 2024

Abstract In this work, a numerical evaluation of the melting/solidification performance phase change material (PCM) filled inside triplex‐tube latent heat storage unit has been carried out. To enhance performance, porous Cu metal foam (MF) was embedded PCM (termed as composite PCM). Alternative segments pure and have allocated in such way that both occupy equal annular area (i.e., volumes). Influence increasing number delineated on rate, complete melting time, thermal energy storage/recovery enhancement. The comparisons were drawn with reference to model having two PCM. results show containing 64 alternate allocations faster rate than other models. With 32 MF, full time reduced by 23%/77% respect case one segment MF only. gets saturated beyond (M‐5) negligible variation (only ~1%) noticed upon further segmentation. Finally, M‐5 proved best considering aspects augmented associated complexities. Moreover, heterogeneity applied 32‐segment confirmed anisotropic an increased leads over random isotropic distributions MF.
