Coating Flows and Contact Line Models
A lubrication-type model is developed for gravity-driven coating flow down an inclined plane. The shear-stress singularity at the contact line and different approaches to removing it are discussed. Other topics include the classical Landau–Levich problem and capillary spreading of liquid droplets on flat solid surfaces. Stability of the two-dimensional gravity-driven coating flow and growth of fingering pattern in the strongly nonlinear regime are investigated.
