Résumé

An ice slurry is a mixture of fine ice particles and water or some other aqueous solution that is used to store and transport thermal energy. When ice slurries are cooled from outside, the freezing of the ice slurry in the pipe might occurs, and it causes the blockade of the pipeline. Thus, it is important to predict the freezing behavior of the ice slurry. The freezing behavior of ice slurries is affected by several parameters, such as the flow behavior, ice packing factor (IPF), and freezing direction. However, the effects of these parameters on the freezing behavior have not yet been revealed. This study experimentally investigates the freezing behavior of an ice slurry in a rectangular channel under various conditions. The experiments are performed by varying the IPF of the ice slurry, the Reynolds number of the flow, including both laminar and turbulent conditions, and the location of the cooling surface. The results show that the frozen layer of the ice slurry grows faster than that of an ethanol solution. Moreover, the growth of the frozen layer is relatively insensitive to changes in the Reynolds number, IPF, or location of the cooling surface.
