The aim of this study is to improve the performance a heat exchanger (triplex tube). To achieve aim, contact surfaces were increased by lessening thickness fins in previous model. This provides additional and enables distribution throughout with new T-shaped using computational fluid dynamics (CFD) simulation tool. Two-dimensional numerical models exchangers tube) filled PCM developed. effects various fin geometric properties, including length, thickness, width, on liquid fraction temperature examined, along impact (HTF) melting time. proposed model validated experimental studies, as results provide compromise solution. demonstrated that novel configuration triplex tube exhibits superior distribution, time ratio 33.5% lower compared conventional fins. area was reduced 36 mm², allowing for an increase amount PCM. These findings strong foundation further research development storage units. Additionally, there potential incorporate rotational system into technique enhance energy storage.
