  In this paper we investigate dynamic wetting in the curtain coating
configuration. The two-phase Navier-Stokes equations are solved by a
Volume-of-Fluid method on an adaptive Cartesian mesh. We introduce the Navier
boundary condition to regularize the solution at the triple point and remove
the implicit numerical slip induced by the cell-centered interface advection.
We use a constant contact angle to describe the dynamic contact line. The
resolution of the governing equations allows us to predict the substrate
velocity at which wetting failure occurs. The model predictions are compared
with prior computations and experimental observations.
