Flows induced by sorption on fibrous material in a two-layer oil−water system

Abstract

The processes of sorption on fibrous materials in the open elliptic cell filled with a two-layer oil−water liquid at rest are investigated experimentally. When the sorption efficiency dependent on the type of material proves to be reasonably high, large-scale flows are formed in the liquid. In this case, the uniformity of distribution of oil is violated and the free surface of the water is partially restored. The trajectories of motion of individual oil droplets on a released water surface are tracked, and the transfer rates are calculated in various phases of the process.
