Surface Tension with Smooth Particle Hydrodynamics

Abstract: With SPH there are generally two ways to model the surface tension effect: one is based on a macroscopic surface tension model; the other one uses microscopic inter-phase potentials. The approach using a macroscopic surface-tension model usually defines a color function, and recovers the prescribed surface tension. However, the implementation is complicated. On the other hand, the implementation of an inter-phase potential is straightforward, but the difficulty is that the resulting surface tension needs to be calibrated, and if not carefully implemented may not converge as the resolution is refined. We use an inter-phase potential to recover surface tension in a multiphase flow, and report our recent progress.
