Experiments have been performed to investigate the ice-formation phenomena and the heat transfer characteristics for water flow between two horizontal parallel plates. The experiments were carried out under the condition that the upper and lower plates were cooled at the same uniform temperature, which was less than the freezing and the temperature of the water. The temperature of the plates ranged from −7 to −14°C with inlet-water temperature varied from 2 to 5°C. The cooling-temperature ratio θc ranged from 1.4 to 7.0. By using three different values of height H, 16, 30, and 40 mm between the horizontal parallel plates, the Reynolds number ReH were varied from 3.8 × 103 to 3.2 × 104 . As a result of the present investigation, two different types of ice-formation were observed. One was transition ice-formation type, and the other was smooth ice-formation type. It was found that the transition ice-formation type occurred for ReH /θc 0.741 < 104 , while the smooth ice-formation type occurred for ReH /θc 0.741 > 104 . The relation equations for the ice-transition position and the heat transfer coefficients along the water-ice interface were extensively determined.
