Close-contact melting heat transfer characteristics, including natural convection in the liquid region in cylindrical capsules, were studied theoretically. Elucidation of such heat transfer mechanism is of much importance from the viewpoint of cost-effective ice storage and heat storage systems employing the latent heat-of-fusion thermal energy storage (LHTES) concept. This paper presents full transient numerical solutions for combined close-contact and natural convection melting heat transfer in cylindrical capsules. Then, the validity of the previous approximate equations is examined. Moreover, the computer simulation of thermal performance for the latent heat thermal energy storage unit using cylindrical capsules was also performed. It facilitates the designing of the practical LHTES systems using various capsules.
