Abstract Thermocapillary-driven convection in a hanging droplet is experimentally investigated under normal- and micro-gravity conditions. A droplet is hung on a heated cylindrical rod facing downward, and another rod cooled is placed just beneath the droplet to create the designated temperature difference between both ends of the droplet. A transition of the flow field from a two-dimensional axisymmetric ‘steady’ flow to three-dimensional time-dependent ‘oscillatory’ ones by increasing temperat...

The present authors carried out an experimental study with a special interest upon the dynamics of the fluid in the vicinity of the boundary lineof three phases; solid-liquid-gasin- terface, which is so-called 'contact line.' The moving droplet on the solid substrate is accom- panied with the movement of the boundary line of three phases; solid-liquid-gas interface, which is so-called macroscopic 'contact line.' Existing studies have indicated there is a thin liquid film known as 'precursor film...
