Transition in a numerical model of contact line dynamics and forced dewetting

- A novel numerical model is developed for the transition in a numerical model of contact line dynamics and forced dewetting using Volume-of-Fluid method.
- We investigate angles from 15° to 110°, capillary numbers from 0.00085 to 0.2, and mesh sizes from 0.0035 to 0.06 of the capillary length.
- We extend the current theoretical framework to include arbitrary angles and viscosity ratios. We show that the numerical results are in agreement with this theory.
- We identify a microscopic length found in the simulations and relate it to the numerical slip length.
- The knowledge of this microscopic length scale can be used to realize gridindependent simulations of general fluid-mechanical problems involving dynamic contact lines.
