Abstract

A flow visualization system has been used to obtain the heat transfer distribution and the region of melting around a circular cylinder that is placed in a solid close to its melting point. The measurement makes use of direct flow visualization and observation of the pattern of the molten region to determine the heat transfer rate on the outer interface between the liquid and the melting solid. Naphthalene close to its melting point is used as the melting material. Preliminary measurements show the results for melting with virtually no subcooling. The experiments agree with a previous study of heat transfer through concentric annuli in that the heat transfer rate at the lower melting surface is extremely small. Use of such a system will permit optimization of the geometry of heating tubes in a thermal energy storage system. (A)
