Melting heat transfer from a horizontal ice cylinder immersed in sea water.

Abstract

An observational study has been preformed to investigate the melting behavior of a horizontal ice cylinder immered in quiescent sea water. The experiments were carried out in 3.5 % sea water for the ambient temperatures ranging from 2.8 to 20.3°C. It was observed that the flow consisted of a laminar bidirectional flow for the lower part of the ice cylinder and of a turbulent upward flow for the higher part of the cylinder, and that the ice surface was roughened by a secondary flow caused by an instability based on the buoyancy force in the boundary layer flow. It was also found that the heat-transfer characteristics were markedly affected by the equality of the flow in the boundary layer.
