    Description / Table of Contents: The transition in the mode of heat transfer from conduction to convection in a layer of water formed continuously by melting ice from below has been determined experimentally. This was accomplished by locating the inflection point on the curve relating the water-ice interface (or melting front) and time. Thus, the critical Rayleigh number, Rac, at which convective heat transfer started can be correlated empirically as a function of warm plate temperature, Ts, by Rac= 14,200 exp(-6.64 x 10^-2 Ts). This relation is valid for Ts varying from 7.72 to 25.50°C. The initial ice temperature T0 was varied from -4.8 to -22.00°C. The effect of T0 was found to be insignificant. Homogeneous, bubble-free ice was prepared and used in all the experiments.

    Description / Table of Contents: The flow of a compressible fluid through a deep layer of a porous medium with non-uniform permeability was analyzed. The volumetric behavior of the fluid was described first by the perfect gas law, then by the van der Waal's equation of state. Darcy's law was assumed to be valid. For illustration, the model of air flowing through a deep bed of naturally compacted snow was used to carry out numerical computation. The permeability of snow was considered as a function of depth. The nonlinear partial differential equation obtained by combining the continuity equation with Darcy's law was solved by finite difference technique. A time dependent exponential decay boundary condition was used which included the step-rise constant boundary condition as a limiting case. Pressure distributions in the porous medium calculated from the assumption of ideal gas and van der Waal's gas were compared. The data were presented in dimensionless variables.

    Description / Table of Contents: An experimental study of the heat transfer characteristics of a bubble-driven water jet on an ice surface was conducted. Two Lucite columns, one 1.829 m high and 0.286 m in diameter and the other 1.219 m high and 0.140 m in diameter were used. Water levels were maintained at 0.762 and 1.524 m in the large column and 0.840 m in the small column. Hypodermic needles with openings of 0.152, 0.406 and 0.838 mm were used for bubble formation. The air flow rate was varied from 7.39 X 10^-8 to 9.91 X I0^-7 m^3/s. In all, 171 experimental runs were conducted. The results can be correlated by Nu = 0.1735 (Rei)^0.848 with a correlation coefficient of 0.84, in which Nu is defined in terms of average heat transfer coefficient h, sample diameter Ds, and thermal conductivity of water kw. Rei is defined in terms of diameter of the impinging water jet at the ice surface, Di, the centerline arrival water velocity vc and the kinematic viscosity of water uw.

    Description / Table of Contents: An experimental study of forced convective heat transfer over a vertical melting plate has been conducted. This study covers water velocities ranging from 1.7 to 9.8 mm/s and bulk water temperatures from 1.11 to 7.50 C. The experimental results are correlated in terms of Nusselt, Prandtl and Reynolds numbers with a moderate correlation coefficient of 0.843. The results are expected to be useful in predicting the heat transfer characteristics of a much larger prototype ice-water heat sink.

    Description / Table of Contents: The heat transfer processes associated with melting and refreezing a drill hole 500 m in depth and 0.150 m in initial radius through an ice shelf were approximately analyzed. The results were expressed in graphical form showing the time available for experimentation under the hole as a function of heating duration and heating strength. It was found that the refreezing of the drill hole had a much slower rate than the melting of the hole.
