The melting of an ice shell on a heated horizontal cylinder

This 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. The melting process consists of two distinct regimes, first, an early regime when the cylinder is surrounded by ice, and second, a late regime when the cylinder cuts through the top of the ice shell. Laboratory measurements that validate the theory are described. In the complete cycle there exists an optimal frozen shell thickness such that the cycle-averaged production of ice is maximized.
