This paper reports both the heat transfer performance and the flow characteristics of slush ice flow between horizontal heated plates. A mixture of fine ice particles and ethylene-glycol aqueous solution was adopted as a testing slush ice and was heated by the top or the bottom wall of the flow channel. Experiments were carried out to investigate the effects of heat flux, velocity of slush ice flow, and channel height of test section on the melting heat transfer characteristics. Both the velocity distribution and the ice packing factor distribution in the flow channel were measured in detail. The results revealed that the forced-convection heat transfer and flow characteristics of slush ice were markedly affected by both the velocity distribution and the ice packing factor distribution near the heated wall.
