Kurzbeschreibung (Abstract)
Wetting scenarios on the micro scale are becoming more important for a variety of engineering applications. The development of manufacturing techniques that can produce surfaces with a defined microstructure is in the scope of current research efforts. This allows to directly manipulate the wetting properties of a surface. Hence, a need for numerical models that can predict the wetting properties of microstructured surfaces arises. Phase field (PF) models can be applied for this purpose. The present PF model for wetting is informed by molecular dynamics (MD) simulations. It uses the MD based perturbed Lennard-Jones truncated and shifted (PeTS) equation of state and an MD based viscosity correlation. This approach ensures a sound physical foundation of the model.
