Dynamics of wetting processes
Abstract
Fluid mechanics were analyzed for some wetting processes using a new mechanism for the origin of flow near a contact line. The basic idea is that intermolecular forces can generate flow in the immediate vicinity of the contact line. The direction and detailed pattern of the flow depends on the difference between the actual and equilibrium configurations of the fluid interface near the contact line. For the special case of equilibrium, equations yield results in reasonable agreement with existing theoretical and experimental findings about equilibrium contact angles for various liquids on the same solid surface. Confidence in the theory's predictions for dynamical situations is thus strengthened. Lubrication theory was used to simplify the equations of motion.
