摘要：

The heat transfer characteristics were experimentally investigated for ice Slurry made from 6.5% ethylene glycol-water solution flow in a 13.84 min internal diameter, 1500 mm long horizontal copper tube. The ice slurry was heated by hot water circulated at the annulus gap of the test section. Experiments of the melting process were conducted with changing the ice slurry mass flux and the ice fraction from 800 to 3500 kg/m(2)s and 0-25%, respectively. During the experiment, it was found that the measured heat transfer rates increase with the mass flow rate and ice fraction; however, the effect of ice fraction appears not to be significant at high mass flow rate. At the region of low mass flow rates, a sharp increase in the heat transfer coefficient was observed when the ice fraction was more than 10%. (c) 2005 Elsevier Ltd and IIR. All rights reserved.
