A lot of solidification and melting phenomena exist in our environment and many industrial processes. The present research focuses on the ice formation around a vertical circular cylinder. The copper cylinder, whose surface was lowered to subzero temperatures by circulating refrigerant, was set vertically in a rectangular container filled with distilled water. The bottom of the container was fixed at 15℃, so that vigorous convection is present during the solidification. The ice layer growth on the cylinder was measured for various cooling temperatures. One dimensional approximate analysis was proposed by considering the heat balance at the solid-liquid interface. The model was solved by the Runge-Kutta technique for transient ice-growth. The average ice-layer thicknesses predicted by the one-dimensional analysis are found to agree well with the experimental results.
