Flows involving moving contact lines (MCLs) are widely found in nature and industry. A major challenge in modelling MCLs is that the conventional hydrodynamic theory combined with a no-slip boundary condition at the wall leads to a non-integrable stress singularity at the contact line. In this seminar I will first review the major theoretical models and computational methods for moving contact lines, and the main associated challenges. Then I will introduce a recent computational model for practical simulations of moving contact lines. The model borrows the idea from the large eddy simulation in turbulence modeling; it resolves the macroscale flows only while model the effect of MCLs using modified hydrodynamic theories.
