An experimental study has been performed to investigate the freezing heat-transfer, characteristics in a return bend with rectangular cross section. The experiments were carried out for two kinds of duct heights of 30mm and 50mm with duct width of 300mm and convex radius of curvature of 159mm under the condition that both the convex and concave walls of a return bend were kept less than the freezing temperature of water. It was found from the present experiment that the freezing behavior on the convex wall was much different from that on the concave wall of a return bend and that the cooling temperature ratio was important parameter on the freezing heat transfer.
