This paper is dealing with the heat transfer characteristics around horizontal cylinders immersed in ice slurry flow. A mixture of ice particles and a trehalose aqueous solution is produced and utilized as a testing ice slurry. The experimental investigation is carried out under some parameters such as a velocity of ice slurry flow, the heat flux of heated surface and a formation of cylinder array. As a result of the evaluation of the local heat transfer coefficient and the observation of the flow behavior, it is found that the distribution of the local heat transfer coefficient is strongly affected by both of the flowing behavior which depends on the formation of cylinders and the melting of ice particles.
