Dynamical deformation of a flat liquid-liquid interface

Résumé

The passage of solid spheres through a liquid-liquid interface was experimentally investigated using a high-speed video and PIV (particle image velocimetry) system. Experiments were conducted in a square Plexiglas column of 0.1 m. The Newtonian Emkarox (HV45 50 and 65% wt) aqueous solutions were employed for the dense phase, while different silicone oils of different viscosity ranging from 10 to 100 mPa s were used as light phase. Experimental results quantitatively reveal the effect of the sphere's size, interfacial tension and viscosity of both phases on the retaining time and the height of the liquid entrained behind the sphere. These data were combined with our previous results concerning the passage of a rising bubble through a liquid-liquid interface in order to propose a general relationship for the interface breakthrough for the wide range of Mo 1/ Mo 2 ∈ [2×10^-5 - 5×10^4] and Re 1/ Re 2 ∈ [2×10^-3 × 10^2].
