Equation of motion of the triple contact line along an inhomogeneous surface
– The wetting flows are controlled by the contact line motion. We derive an equation that describes the slow time evolution of the triple solid-liquid-fluid contact line for an arbitrary distribution of defects on a solid surface. The capillary rise along a partially wetted infinite vertical wall is considered. The contact line is assumed to be only slightly deformed by the defects. The derived...
متن کاملEarthquake Analysis of 3-D Structures on Sliding Foundation Using Yield Equation of the Contact Surface
A solution technique for the dynamic analysis of asymmetric base-isolated buildings, subject to earthquake ground motion, is presented. To develop the formulation, a yield surface as a function of both shear force and torsion moment of the sliding surface with rigid perfectly plastic behavior is constituted. To achieve the objective, the yield stress is defined by the friction coefficient throu...

15 صفحه اولDynamics and depinning of the triple contact line in the presence of periodic surface defects
We propose an equation that describes the shape of the driven contact line in dynamics in presence of arbitrary (possibly random) distribution of the surface defects. It is shown that the triple contact line depinning differs from the depinning of interfaces separating two phases; the equations describing these phenomena have an essential difference. The force-velocity dependence is considered ...
