Experimental study and calculation method of heat transfer coefficient when using ice slurries as secondary refrigerant.

Author(s) : GUILPART J., FLICK D., FOURNAISON L., LALLEMAND A., BEN LAKHDAR M.

Summary

The paper presents an experimental study of transport characteristics of ice slurries made of ice/water/ethanol mixtures. Wall temperature profiles in a circular smooth tube were obtained in fixed flux conditions. Local Nusselt and Reynolds numbers are calculated. Resulting calculated heat transfer coefficients fit experimental data with a good accuracy (plus or minus 13%). Values of 1500 to 2500 watts per m2 degree K were observed and were shown to depend mainly on ice concentration. These values were obtained in experimental conditions similar to many practical situations.
