摘要：

A numerical "macroscopic-scale" method for static (including hysteresis) and moving contact lines for partially wetting liquids is presented The numerical method is based oil the implementation of a "sub-grid" description of the contact line that consists in imposing the apparent angle for static and moving contact lines The numerical simulations are validated against several well controlled bi-dimensional situations the equilibrium shape of a drop released oil a hydrophobic or hydrophilic wall, the axisymmetric spreading of a drop for a partially wetting liquid, the migration of a drop placed on a inclined wall and submitted to a Couette or Poiseuille flow (C) 2009 Elsevier Inc All rights reserved
