Résumé

A new method is proposed for the measurement of the ice packing factor (IPF) of an ice slurry using the index of refraction. The purpose of the new method is to improve the resolution of the measurement and to increase its resistance to electric noise as compared to the standard IPF measurement technique that relies on measurement of the freezing point. These two methods are similar in that they both obtain a concentration of aqueous solution from measured physical quantities and calculate the IPF using a relation between concentration and IPF. The authors experimented and compared the two methods, whose results were also compared with results from the calorimeter method obtaining the IPF directly. They are in good agreement (within 5%) which demonstrates the validity of the newly proposed method.
