Abstract
An experimental study is reported of the melting of a vertical ice layer into an ammonium chloride-water solution, as well as the melting of a vertical ammonium chloride-water eutectic layer into water. The experiments were conducted inside a vertical rectangular cavity with differentially heated side walls. It is found that in both cases the melting process induces the formation of double-diffusive layers in the initially homogeneous liquid. Due to the continuously changing concentrations in each layer, the double-diffusive interfaces can break up, resulting in vigorous mixing of the liquid in the layers. These convection phenomena have a significant influence on the local melting rates. It is observed that the presence of the double-diffusive interfaces in the liquid causes the formation of steps in the solid layer thickness, while the changing height of the double-diffusive layers can even induce resolidification on parts of the remaining solid layer.
