“…Fundamental studies are available in the literature on heat transfer during melting and solidification of phase change materials around cylinders (Rieger et al, 1982;Sasaguchi and Viskanta, 1989;Lacroix, 1993a) or encapsulated in cylindrical (Sparrow and Broadbent, 1982;Ho and Lin, 1986;Prasad and Sengupta, 1988;Wu and Lacroix, 1993) and rectangular cavities (Gadgil and Gobin 1984;Okada, 1984;Ho and Viskanta, 1984;Lacroix and Garon, 1992). The main objective in most of these studies was to evaluate the temperature distribution inside the PCM and to locate the interface position with time during melting and solidification.…”
