Abstract
Fluid flows occurring during solidification of metal alloys influence the composition and the properties of the final solid. Transport phenomena for this process are investigated using a model system: a dissolving drop inside a surrounding liquid under a thermal gradient. Experiments are performed with transparent organic liquids with miscibility gap. Novel mathematical models and numerical strategies are presented to correlate experimental results and in particular to explain the behaviour of stable and unstable solutal plumes that are formed above the dissolving droplet.
