Experimental and analytical studies of the ice formation process with longitudinal fins in an isothermally cooled parallel-plate channel with convective water flow have been performed. The fins made of copper were soldered onto the cold wall parallel to the water flow direction. The resulting thickness of ice formed over the fins was measured under a steady-state condition in the ranges of Re_H = 710〜3060 and cooling temperature ratio of θ= 0.67〜5.13. An analytical method for ice formation associated with large fin spacing with convective water flow is proposed. In the present analysis, ice formation with "heat conductor plates", which are not physically soldered onto the cold wall, is also examined. The effects of spacing, thickness, height, and thermal conductivity of heat conductor plates on the ice volume fraction are investigated.
