Three-Dimensional Modeling of Interfacial Tension with Smoothed Particle Hydrodynamics by Using Pairwise Potential

Abstract

A new pairwise potential was introduced into the three-dimensional SPH simulation program and the dynamic behavior of small droplets on a solid substrate was calculated. The simulation could reproduce the experimental observations for an aluminum droplet on an alumina substrate as well as those of water on glass and Teflon substrates. The program was applied to an iron droplet on an aluminum substrate, and the droplet’s dynamic behavior was estimated.
