| Abstract |
In the present paper, 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 mea-surement of the freezing temperature. 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. We experimented and compared the two methods, whose results were also compared with results from the calorimeter method obtain-ing the IPF directly. They are in good agreement(within 5%), which demonstrates the vali-dity of the newly proposed method. |
