Summary

This article reviews the technologies on preventing the agglomeration of ice particles in water and the drag reduction of ice slurry flow with surfactant additives. A screening test was performed to find a coupling technology of anti-agglomeration and drag reduction with one kind of surfactants. From the test, zwitterion surfactant, cetyldimethylbetaine with sorbitol agents was found to effectively prevent agglomeration of ice particles and reduce friction drag in a pipe flow at a very low concentration less than 2000 ppm without a serious depression of the equilibrium freezing temperature. This is concluded to improve the ability of ice slurries as a secondary refrigerant.
