A Two-Phase SPH Model for Dynamic Contact Angles Including Fluid–Solid Interactions at the Contact Line

Abstract: The description of wetting phenomena on the continuum scale is a challenging problem, since intermolecular interactions, like van der Waals forces between liquid and solid, alter the flow field at the contact line. Recently, these effects were included in the smoothed particle hydrodynamics method by introducing a contact line force (CLF) on the continuum scale. This physically based contact line force model is employed here to simulate two-phase flow in a wide range of wetting dynamics parametrized by capilla… Show more

“…DNS methods such as computational fluid dynamics (CFD) and Lattice Boltzmann methods (LBM) solve pore-scale governing equations in actual pore space obtained from digitalized porous media without modification or idealization (Chen et al, 2015;Guo et al, 2018). In the DNS methods for two phases, modeling the interface by sharp interface models or diffuse interface models, has been an intractable problem (Kunz et al, 2018;Yin et al, 2019;Zhu et al, 2020;Zhu et al, 2019). The moving contact line, defined as the intersection of the fluid-fluid interface with the solid wall, is incompatible with the no-slip boundary condition on the solid wall surface.…”
