Simultaneous charging and discharging of metal foam composite phase change material in triplex-tube latent heat storage system under various configurations

Chemical Product and Process Modeling, Journal Year: 2023, Volume and Issue: 18(5), P. 823 - 837

Abstract Phase change material (PCM) has high latent heat on one hand albeit low thermal conductivity the other which restricts its utilization in energy storage applications. Therefore, to improve performance of PCM, various techniques have been employed. This numerical work intends estimate effect copper metal foam (MF) seven configurations (M1–M7) triple-tube exchanger (TTHX) under simultaneous charging and discharging (SCD) conditions using transfer fluids (HTF) both sides. Five distinct with equal volumes PCM composite (CPCM) considered for optimization standpoint. RT55 (melting temperature = 327 K) is taken as PCM. Based thermo-physical properties boundary heated tube, dimensionless controlling parameters such Rayleigh number ( Ra ), Prandtl Pr Stefan Ste ) were 1.79 × 10 5 , 30, 0.21, respectively. Typical results melt fraction, storage, contours, steady-state fraction corresponding melting time reported. Performance yielded by all was compared a fixed duration 2 h. The positioning MF largely affects mechanism unit. Results show that bottom-side can boost due enhanced buoyancy-induced convection. Among models, M3 predicts highest λ $\lambda $ ss ≈ 0.62) shortest t 66 min), followed model M6 λ 0.58, 65 min). optimized design (model M3) shows ∼75 % enhancement than pure (M1) case. Interestingly, may also achieve ∼17.2 higher M2 but only half mass used full porous configuration (M2).
