Close-contact-melting heat-transfer characteristics, including natural convection in the liquid region of cylindrical capsules, were studied theoretically. Elucidation of such heat-transfer mechanisms is of great importance from the viewpoint of cost-effective ice-storage and heat-storage employing the latent heat-of-fusion thermal-energy storage (TES) concept. The Growth Ring Method (GRM) was used as a numerical tool to handle the moving interface between the liquid and solid regions. The computed isotherms, streamlines, and stored-heat fractions were clarified in detail. In particular, special attention was focused on the role of natural convection in the upper liquid region. Hitherto, no exact numerical analysis has been made to clarify the contribution of natural convection.
