Partial Abstract: Experiments to study the melting of a horizontal ice sheet with a flow of water above it were conducted in a 35-m-long refrigerated flume, with a cross section of 1.2 x 1.2 m. Water depth, temperature, and velocity were varied as well as the temperature and initial surface profile of the ice sheet. The heat transfer regimes were found to consist of forced turbulent flow at high Reynolds numbers with a transition to free convection heat transfer. There was no convincing evidence of a forced laminar regime. The data were correlated for each of the regimes, with the Reynolds number, Re, or the Grashof number combined with the Reynolds number as Gr/Re^2.5 used to characterize the different kinds of heat transfer. NOTE: The remainder of the abstract contains several complex mathematical equations difficult to render on this system. The downloaded will contain the rest of the abstract as well as the document.
