- ABSTRACS Heat transfer in a latent thermal energy storage during melting process heated by a surface of constant wall temperature has been studied experimentally and analytically. Theoretically, the melt layer for the subcooled PCM is thinner than that for un-subcooled. The experimental results show that the reaching time of melting temperature for the points located at the same radius depend on their angular positions. The points located at the vertical axis arrive faster at the melting temperature than those at 45°C from that axis. From time-temperature histories'point of view, the experimental results show the reaching time of melting temperature at the particular points are faster than the theoretical ones. The two facts mentioned above indicate that during melting process, natural convection occurs in the liquid phase and supports the interface at the upper part of the tube. Key word: experimental apparatus, heat transfer, melting
