Surface Tension Model for Free-Surface Problems in SPH
This paper presents a surface tension model for Smoothed Particle Hydrodynamics. This model originates from previously published models based on the Continuum Surface Force approach. Its main feature is how it deals with the free surface, where particles suffer from particle deficiency. The model is tested in two dimensions using oscillating and static cylindrical rod problems. Its sensitivity to spatial resolution was evaluated, and some of the model's features discovered. Overall, the model seems to provide accuracy sufficient for most practical applications.
