Low Shear Rates

Abstract
At an oil-water boundary on a solid surface, the hydrophobicity of a solid surface
can be represented by the displacement energy, which is dependent on the
properties of the emulsifying agents. The tendency of oil to displace water can be
estimated by considering the displacement energy. An interesting property of oilin-
water (o/w) that has attracted the attention of tribologists, is their ability to
form thicker hydrodynamic films than those expected from their apparent
rheological properties. To study this phenomenon, experiments have been
conducted on a specially designed viscometer rig, with different o/w
concentrations. The rig is composed of a metal tube with straight and uniform
parallel ground bore and droppers of PTFE material, which are allowed to
descend at micro-clearances in the vertically positioned tube filled with the
