Scale bridging simulation of dynamic wetting based on the phase field method (B07)

• Subject Area: Chemical and Thermal Process Engineering
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 265191195

The aim of B07N is the fundamental understanding of local transport processes at the contact line in multiscale, dynamic wetting processes on complex substrates. A proprietary CFD-solver based on the diffuse-interface phase field method and developed in OpenFOAM will be used. The method enables the description of imbibition and penetration processes in porous/structured substrates, especially during capillarity dominated wetting. Focus lies on the exact detection of local heterogeneities (pore size distribution, rough-ness, functionalization) as well as on a scale bridging methodology, to be realized by combining modern HPC techniques, DG methods and the hybrid atomistic-continuum method.
