Abstract
Visual observations reveal a complicated flow in the liquid melt and a melting front configuration resulting from horizontal ice plate melting from above into a 20 wt% calcium chloride aqueous solution. The initial temperature of the ice plate and the mixture are both -5°C. Small scale ``mountain and valley'' structures (∼1 mm) appear on the flat melting front just after melting begins, which have been called ``sharkskin''. Innumerable upward and downward flows appear near the sharkskin and are controlled by its ``mountain and valley'' structure. These typical flows will considerably promote the melting of the ice plate to be 30% larger as compared to the numerically predicted results assuming a flat melting front (i.e., without the sharkskin), and also by three times larger compared with the results for melting from below.
