Modeling and VOF-based multiphysics simulation of irreversible thermodynamic transfer processes at dynamic contact lines (B01)

• Subject Area: Mathematics
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 265191195

In B01, the fundamental understanding of local processes at dynamic contact lines will be enhanced by rigorous modeling of contact angle hysteresis, dissipation and rolling motion at the contact line. The sec-ond focus lies on further development of the geometric Volume of Fluid method. Here the treatment of dy-namic contact lines from FS3D has to be transferred to the case of unstructured, dynamically adaptive grids using voFoam in OpenFOAM. Regarding the simulation of, especially, the generic configurations in cooperation with A01, A02 and A05, further numerical developments are planned, for example concerning the wetting of rough surfaces, treatment of pinning and contact angle hysteresis as well as visco-elastic flow behavior.
