Abstract
Flow characteristics of ice slurry in narrow tubes were investigated experimentally. IFF, velocity of the ice slurry and diameter of the tubes were varied as the parameters, and measurements of pressure drop were carried out. As a result, in laminar flow region, the coefficient of pipe friction increased with the IFF. In turbulent flow region, the effects of the IFF on the coefficient of pipe friction were not significant in the case of small IFF. On the other hand, in the case of large IFF, the coefficient of pipe friction increased with the IFF. Moreover, the flow characteristics can be clarified using apparent Re number, which is decided by considering the ice slurry as pseudoplastic fluid.
