Résumé

The study investigated experimentally effects of additives on the size of ice particles in ice slurries. Ethanol solution was used as aqueous solution to make ice slurries and PVA (poly-vinyl alcohol) and glycerin were examined as additives. The aqueous solution was kept in supercooled condition, and ice slurry was subsequently made by releasing the supercooled condition. The degree of supercooling and concentrations of additives were varied as parameters. The observations of the ice particles in the ice slurry were carried out just after generation of the ice slurry and after 24 hours of storage. Differences between with and without additive was not observed just after generation, and dendritic ice appeared in both cases. However, finer ice particles were observed after 24 hours storage in a case of the solutions with additives.
