Abstract
An experimental study was performed to control Ice Packing Factor (IPF) of ice slurry in a pipe in a real time. This paper presented the concept that IPF can be adjusted by the amount of the solution contained to ice slurry. Based on this concept, we designed IPF controller consisting of the outlet tube providing ice slurry and the upper tube discharging only a solution through holes, and investigated the technical validity and efficiency of the controller experimentally. As a result, the original proposed IPF controller could not control IPF of ice slurry in a pipe. This is because an ice of ice slurry was drained out into not only the outlet but also the upper of the controller due to the size of the holes relatively large compared to the ice particle. Therefore, we changed the hole size of IPF controller surface using fine meshes and then, observed that IPF in a pipe was increased by
