Franchissement d'interface et enrobage d'une sphère

Abstract : The passage of a sphere through a liquid-liquid interface is studied experimentally in the particular case of a highly viscous upper liquid. For low values of the modified Bond number β the motion of the sphere consists of two distinct regimes: a slow draining stage of the upper liquid film trapped between the sphere and the interface, and a rapid one where a liquid tail bridges the sphere to the upper phase. It is found that the volume of liquid carried away by the sphere varies as ln β and that the time necessary for breakthrough varies as l/ln β.
