Melting Heat Transfer along a Horizontal Heated Tube Immersed in Liquid Ice

抄録

Experiments have been performed to investigate melting heat-transfer characteristics along a horizontal heated cylinder immersed in a liquid-ice layer. A mixture of fine ice particles and ethylene glycol binary solution was utilized as the testing liquid ice. The experiments were carried out for a variety of parameters, such as heated-tube diameter, heat flux, and initial concentration of the aqueous binary solution. Attention was mainly focused on visual observation of the melting behavior and on its mechanism. The results revealed that the melting interface of the current liquid-ice layer might advance, in general, rather horizontally, unlike the normal melting observed in common rigid ice and PCM.
