Melting characteristics along a bundle of horizontal heated cylinders immersed in a liquid ice layer

Experiments were performed to investigate the melting of liquid ice along a bundle of horizontal heated cylinders. A mixture of fine ice particles and ethylene glycol aqueous solution was adopted as the liquid ice for the test. In one set of experiments, the liquid ice was a quiescent layer, whereas in a second set of experiments the liquid ice was a fluidized bed layer. Measurements were carried out for a range of parameters such as initial concentration of aqueous binary solution, heat flux, and airflow rate for fluidization. The heat transfer coefficient for the fluidized liquid ice bed was found to be more than 25 times as large as that for the quiescent liquid ice bed.
