Pressure drop and heat transfer characteristics of ice slurry in a tube type heat exchanger.

Author(s) : LEE D. W., LEE S. M.

Summary

To clarify the hydraulic and thermal characteristics of ice slurry which was made from 6.5% ethylene glycol-water solution flow in the tube-type heat exchanger, experimental studies were performed. The pressure drops and heat transfer rates of ice slurry were measured in a 0.5 inch copper tube. The mass flux and ice fraction of ice slurry varied from 800 to 3,500 kg/m2s and from 0 to 25%, respectively. During the experiment, it was found that the measured pressure drop and heat transfer rate increase with the mass flux and ice fraction; however the effect of ice fraction appears not to be significant at high mass flux region. At the region of low mass flux, a sharp increase in the pressure drop and heat transfer rate were observed when the ice fraction was more than certain value depends on mass flux.
