Storage and mixing of ice slurries in tanks

Experimental results on storage and mixing of ten-percent-talin/water ice slurries are presented. For this purpose a system with a storage tank, with a volume of 1000 liters and a mixing device containing three slightly inclined cones, was investigated. In first experiments the angular velocity of the mixing device was varied. The variance of numerous temperatures (measured at different locations with different heights in the tank) yields a suitable measure to quantify the stratification. Above a critical rotation frequency, which is a function of the ice fraction, the entire fluid gets into motion and very good mixing is obtained.
