Although the contact angle between a liquid/vapor interface and a flat homogeneous solid at equilibrium is well explained at equilibrium, the motion of the triple line line is still not well understood. A mobility equation relates the deviation of the contact angle out of its equilibrium value and its speed on the solid.

A phase-field moving contact line model with soluble surfactants
Journal of Computational Physics, 2020A phase-field moving contact line model is presented for a two-phase system with soluble surfactants. With the introduction of some scalar auxiliary variables, the original free energy functional is transformed into an equivalent form, and then a new ...

Microscopic Origin of Capillary Force Balance at Contact Line.
Physical Review Letters, 2020We investigate the underlying mechanism of capillary force balance at the contact line. In particular, we offer a novel approach to describe and quantify the capillary force on the liquid in coexistence with its vapor phase, which is crucial in wetting ...

The flow field around a moving contact line, generated by an impulsive, horizontal motion of a vertical plate, is studied numerically. The two‐dimensional, unsteady Navier‐Stokes equations, coupled with the kinematic and dynamic boundary conditions on the free surface, are solved.

Line tension vector thermodynamics of anisotropic contact lines
Physical Review E, 2004Multiphase materials with intersecting diving surfaces give rise to contact lines. A line tension vector thermodynamics formalism is developed and used to analyze contact line problems in the presence of anisotropy, taking into account two elastic modes: change in contact line length and change in contact line orientation.

Complex manifolds \(X\) which carry a complex contact structure, i.e., a non-degenerate subbundle \(F\subset T_X\) of the tangent bundle of corank one, appear naturally as twistor spaces over Riemannian manifolds with quaternionic-Kählerian holonomy group. These manifolds have recently gained considerable interest.

Contact-line fluctuations and dynamic wetting
Journal of Colloid and Interface Science, 2019The thermal fluctuations of the three-phase contact line formed between a liquid and a solid at equilibrium can be used to determine key parameters that control dynamic wetting.We use large-scale molecular dynamics simulations and Lennard-Jones potentials to model a liquid bridge between two molecularly smooth solid surfaces and study the positional ...
