Wetting processes with ALE interface tracking

A method to simulate wetting processes by OpenFOAM's ALE interface tracking method is presented. With this approach, a variety of dynamic contact angle models can be run-time selected. Numerical results are compared to an approximate analytical solution for the rise of a liquid in a capillary. Furthermore, the implementation is validated by comparison to experimental data for the reorientation of a free liquid interface in a partly filled right circular cylinder upon gravity step reduction.
