This article deals with laboratory experiments and numerical simulations of convection and dissolution phenomena in partially miscible liquids. Transparent organic liquids (cyclohexane and methanol) are considered as a model system to study problems occurring during solidification of metal alloys with a miscibility gap. Non-invasive optical techniques are used to study stable and unstable convective solutal plumes, that are produced at the tip of a liquid droplet dissolving in a non- isothermal partially miscible liquid. Numerical simulations explain the observed behaviour and capture additional insights into the physics of the phenomenon, following from a delicate balance between counteracting buoyancy and surface tension- driven flows.
