Horrocks), this was following the comment `Use a semi-empirical model for the dynamic contact angle. The attached paper suggests a couple of these, but others exist as well.' from a `senior developer' at CFX. ---=note-separator=--- (private-note)Finally, to complete the picture of slip conditions, we have to mention `numerical slip' often used, especially in the volume-of-fluid codes, to relieve the stress-singularity (e.g., Renardy, Renardy \& Li 2010, van Mourik, Veldman,\& Dreyer 2005). In this approach, the slip length is linked to the size of the mesh elements, so that the resulting numerical solution becomes mesh-dependent.' (Shikhmurzaev 2008, p. 150). `In the fluid-mechanical context, the velocity-dependence of the dynamic contact angle given by (3.80) becomes a particular form of the function \$f\$ in equation (3.41) employed in different forms by the slip models. For example, Petrov \& Petrov (1992) combined (3.80) with Cox's formula (3.57) for one of the `apparent' contact angles; van Mourik, Veldman, \& Dreyer (2005) used (3.80) in a volume-of-fluid code that essentially implements `numerical slip'; etc.' (ibid, p. 172)}, day = 1, doi = {10.1007/bf02872093}, file = {van_mourik_05_simulation_33555.pdf}, interhash = {201ccb80d93e651ccff5821c5a648531}, intrahash = {43eea414268ebab4e8f7ef96bff483b3}, journal = {Microgravity - Science and Technology}, keywords = {vof 76d45-capillarity-in-viscous-fluids moving-contact-line}, number = 3, pages = {87--93}, posted-at = {2008-10-30 05:35:24}, priority = {5}, timestamp = {2021-06-28T03:35:37.000+0200}, title = {{Simulation of capillary flow with a dynamic contact angle}}, url = {http://dx.doi.org/10.1007/bf02872093}, volume = 17, year = 2005 }
