Hiroyuki Kumano, Auteur ; Tetsuo Hirata, Auteur ; Yosuke Hagiwara, Auteur |The effect of storage on flow and heat transfer characteristics of ice slurry was investigated experimentally. After ice slurry had been stored in the storage tank, variations in ice particle size were measured using a microscope, and diameter d[...]

Hiroyuki Kumano, Auteur ; Tetsuo Hirata, Auteur ; Ryouta Shouji, Auteur |Heat transfer characteristics of ice slurry were investigated experimentally. The Reynolds number, diameter of the tubes and ice packing factor (IPF) were varied as experimental parameters. For laminar flow, it was found that the ratio of the Nu[...]
