Résumé

This paper addresses a numerical and experimental investigation of a cold thermal energy storage system involving phase-change process dominated by heat conduction. The problem involves a fluid flowing inside a horizontal finned tube surrounded by a phase-change material (PCM). The objective of this paper is to predict the temperature distribution, the phase front distribution along the tube and to analyze the effect of fin density and size on the dynamic performance of the system. Finally, time-wise variation of energy stored by the system is evaluated through instant images of solidification fronts and the combined effect of fin parameters and the flow rate on energy storage is discussed.
