Hydrodynamic theory of forced dewetting
WebThe forced wetting or dewetting of a solid is an im-portant feature of many environmental and industrial flows. In typical applications such as painting, coating, or oil recovery it … Webvaries with the capillary number as in the Molecular Kinetic Theory [44]. In Sec. 7, we apply the concepts developed above to describe an improved procedure for obtaining grid-independent computations of problems with dynamic contact lines. Finally, we draw our conclusions in Sec. 8. 2. Problem setup: forced dewetting

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. WebSeveral theories explain the dynamic contact angle as a function of wetting or dewetting speed of the contact line on various length scales. Two prominent examples are the …
