The melting of an ice shell on a heated horizontal cylinder.

Summary

The paper describes the fundamentals of melting when a shell of phase-change material rides on a heated horizontal cylinder. Contact melting theory is used to predict the history of the melting process and, in particular, the time when the remaining ice falls off the cylinder. It is shown that the melting process consists of two distinct regimes, first, when the cylinder is surrounded by ice and, second, when the cylinder cuts through the top of the ice shell. Laboratory measurements validated the theory. In the complete cycle that starts with freezing the shell and ends with the contact-melting removal of the shell, there exists an optimal frozen shell thickness such that the cycle-averaged production of ice is maximized.
