This paper presents the flow behavior and heat transfer characteristics of an ice slurry flow through a crank-shaped channel. A trehalose aqueous solution is utilized as the liquid phase for the testing ice slurry.Trehalose is a naturally derived disaccharide composed of two glucose units which inhibits the growth of ice crystals. Specific parameters and features are considered throughout experimental investigation including the ice slurry flow velocity, heat flux of the heated surface, and the channel dimension. Evaluation of the local heat transfer coefficient and observation of flow behavior indicate that the distribution of the local heat transfer coefficient is strongly affected by both the flow behavior at the corner section of the test channel and the latent heat of the ice particles.
