Résumé
Fins are widely recognized as a highly effective solution to address the poor thermal conductivity of phase change materials (PCMs) and enhance the efficiency of phase transition processes in thermal energy storage units. Despite the development of numerous advanced novel fin designs in academic research, their practical application in industry is often limited by the complexity of manufacturing. This study proposes a non-complex yet efficient axial bent fin design aimed at accelerating ice formation in a triplex-tube ice storage unit, with no intricate fabrication techniques. Using time-dependent computational simulations, the impact of key fin variables, including bend angles and directions are thoroughly investigated on the freezing process. The results demonstrate that although the presence of bends weakens the heat exchange in some cases, in the majority of the cases, they lead to improved performance. The findings demonstrate that the bent fin design can increase the freezing rate by up to 42.37% compared to the system without fins and by 6.13% in comparison with the case with traditional straight fins while maintaining identical heat transfer areas and PCM volumes. Given the simplicity of this design, it presents a viable option for real-world implementation in thermal energy storage applications.
