In this study, the initial process of the solidification of flowing supercooled water was investigated analytically. In the process, thin ice propagates on the heat transfer surface toward upstream after the solidification nuclei appeared in the flowing supercooled water, and the dendrite ice grew and melted after growth of thin ice. The calculation model was proposed to reproduce the transient process in the flowing supercooled water, and the growth and the melting of the dendrite ice were calculated. In calculation, the inlet temperature of the water, the average flow rate and the surface temperature of the heating plate were varied as parameters. As a result, it was found that the flow disturbed by the dendrite ice at the upstream region melts the dendrite ice at the downstream region and the calculation model in this study can reproduce the solidification process. Moreover, the effects on the solidification process was examined when the parameters were varied.
