Stribeck Curve for Starved Line Contacts
Journal of Tribology, 2006This paper discusses a mixed lubrication model in order to predict the Stribeck curve for starved lubricated line contacts. This model is based on a combination of the contact model of Greenwood and Williamson and the elastohydrodynamic (EHL) film thickness for starved line contacts.

A multiscale expansion approach is applied to the solution of the free-boundary Stokes’ problem describing flow in the vicinity of a moving contact line. A solution free of singularities is obtained for the case of a liquid advancing into an inviscid medium.

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.

The elasticity of a contact line
Physica A: Statistical Mechanics and its Applications, 1999Abstract We calculate the work required to deform a three-phase contact line between two fluid phases and one solid phase using an interface displacement model. This includes the effects of both surface and line tensions. The leading-order dependence on the wavenumber q of the distortion has been described by Joanny and de Gennes (J. Chem.

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.

12. The sequence of the following problems, fourteen in all, is settled by their interdependence one upon the other. This order, however, is not the most suitable in which to consider the problems as a whole, and to obtain a clear idea of the ground covered the student should rewrite them in outline, as a preliminary, in the manner and order given ...

Effect of contact line roughness on contact angle
Mendeleev Communications, 1996The generalized Young equation allowing for the roughness of the three-phase contact line has been derived and applied to an explanation of experimental results on the contact angle anisotropy of a sessile drop on deformed elastomers.

Instability mechanism at driven contact lines
Physical Review E, 1993An explanation of the mechanism for the fingering instability at driven contact lines is presented. Semiquantitative predictions for the growth of the fingers as a function of time, the most unstable wavelength, and the initial growth rate are deduced. These predictions are consistent with recent experiments of de Bruyn [Phys. Rev. A 46, R4500 (1992)].

Thermodynamics of soft anisotropic contact lines
The Journal of Chemical Physics, 2004Contact lines arising from the intersection of interfaces between liquids and nematic liquid crystals are representative models of soft anisotropic contact lines. This paper presents the thermodynamics of soft anisotropic contact lines and the derivation of the one dimensional (1D) Gibbs–Duhem adsorption equation. Consistency between the 1D Gibbs–Duhem
