N2 - In the growing age, scientists discovered new technology for fish cooling, using ice slurry. Having a Globural shape, Ice Slurry have better quality of cooling than any other dendritic ice. In general, when the ice slurry flow is not sufficiently high the particles will not be maintained in suspension. The purpose of this study was to examine the drag reduction as the ice slurry is released using a spiral pipe. This research investigates two variation of pipes: spiral pipe and non-spiral pipe, with hydraulic diameter of 1 inch and pitch/diameter ratio 6,7. The working fluid is mixture of freshwater with 15% concentrations of glycol. The ice fraction varying at 3%, 6%, 9%, 12% and 21%. Visual observation were also done to investigate the system performance and the rheology of ice mud particles in the spiral pipe made of transparent acrylic. The drag reduction occured significantly in the flow of ice slurry in a spiral pipe. Spiral pipe with a difference of p/d ratio also produce different flow speeds. It can be seen that the use of spiral pipes to run off ice slurry can significantly reduce the resistance that occurs to the fluid. With the proof of the drag reduction of the spiral pipe flow when compared with the round pipe up to 32% in the ice fraction 6% and Re 4438,8.
