In contrast to quasi-static theories based on a dynamic contact angle, we demonstrate that the transition strongly depends on the large scale ow geometry. We then establish the dispersion relation for large wavenumbers, for which we nd that ˙is linear in q. The speed dependence of ˙is well described by hydrodynamic theory, in particular the

Web19 mei 2008 · By using a mean field continuum description, we generalize the capillary pressure from variation of the free energy and show at what length scale the equilibrium contact angle is selected. After recovering Young’s law for homogeneous substrates, it is shown how hysteresis of the contact angle can be incorporated in a self-consistent fashion.
