Summary

Results of an experimental study of the convective heat and mass transfer processes for downward freezing from a horizontal surface into seawater at 35 per thousand, ie at oceanic salinity, are presented. Supercooling before freezing allowed the possibility for density extremum effects to arise under some conditions of low ambient water temperature and large extracted heat flux. After freezing, however, flow visualization revealed that the flow was downward, below the freezing surface. Ice layer and water-ice interface salinities were only weakly dependent on the ice growth rate. Convective heat transfer rates were strongly affected by solute rejection upon freezing.
