Résumé

This paper presents the flow and heat transfer characteristics of an ice slurry flow through cylinder arrays. A mixture of ice particles and trehalose water is utilized as the testing ice slurry. Experiments are carried out under some parameters such as a velocity of the ice slurry, a heat flux, and a layout of cylinder array. The distribution of the local heat transfer coefficient on the surface of a heated cylinder is evaluated. In addition, flow behavior in the test section is observed carefully as well. Experiments using an aqueous solution as a testing fluid are also carried out, and the specific characteristics of ice slurry relative to single phase liquid are discussed. It is found that the staggered layout of cylinders shows higher heat transfer coefficients than the aligned layout setting.
