Phase change phenomena in horizontal cylindrical capsules located in fluid flow were considered both analytically and experimentally. In a single-capsule model, the wall temperature was determined by considering the balance between the wall heat flux and the outer flow heat transfer. By stacking these models, the phase change phenomena of capsules in alignment with flow are analyzed. The analytical results show good agreement with experimental results. According to the results, the main heat exchange at a certain time occurs in some capsules around a certain capsule, and the range of capsules goes down to the flow direction. This model will be useful in optimal designing and controlling of the energy storage system.
