MELTING HEAT-TRANSFER FROM A HORIZONTAL ICE CYLINDER IMMERSED IN QUIESCENT SALINE WATER

The melting characteristics of a horizontal circular ice cylinder immersed in quiescent saline water were determined experimentally. The experiments were carried out in 3.5 wt% saline water for ambient liquid temperatures ranging from 2.8 to 20.3-degrees-C. It was observed that the flow consisted of a laminar bidirectional flow at the lower portion of the melting ice cylinder, and an upward turbulent flow at the upper portion of the cylinder, and that the melting ice surface was characterized variously by secondary flow caused by instabilities based on buoyancy forces in the boundary layer flow. It was also found that the melting heat transfer behavior was markedly affected by the character of the flow in the boundary layer.
