Resumo

Calculations were performed for the melting of ice in a rectangular cell surrounded by a hot wall with conducting fins and an opposing insulated wall. Systematic calculations were performed changing the temperature and the orientation of the hot wall. It was seen that for the hot-wall temperature of 8 °C, the melting rate was larger for the melting from above than that for the melting from below, due to the density-inversion of water. The effect of the conducting fins on the the heat-transfer enhancement was fairly large for both positions of the hot wall. When the temperature of the hot wall was increased up to 16 °C, the effect of the density-inversion in the fluid flow was not clearly appeared, and the melting process was similar to that of materials without density-inversion.
