Smoothed Particles Hydrodynamics

Abstract We compare two surface tension models to solve two-phase fluid interaction problems in the context of the mesh-free Smoothed Particles Hydrodynamics (SPH) method. The Continuum Surface Force (CSF) model (later extended to Continuum Surface Stress, CSS), originally derived from grid-based numerical methods, requires an accurate estimation of the interface curvature to express the surface tension. Unlike CSF, the Inter-Particle Force (IPF) model is more robust in this regard as it draws on a molecular dynamics foundation by considering how the pairwise interaction forces between particles within a cutoff distance act in relation to producing the surface tension. Herein, we rely on second-order consistent gradient and Laplacian operators to improve the accuracy of SPH formulations as well as on a particle shifting technique to “disorder” particles from non-differentiable interface geometries. A 3D liquid droplet deformation test is used to compare CSF and IPF in terms of their pressure field and kinetic energy dissipation accuracy.

The Arlequin method gives a simple and effective framework to glue models using various formulations. It is extended here in explicit dynamics and used in order to link a zone showing ruptures by fragmentation meshed with Smoothed Particles Hydrodynamics (SPH) and a larger second undamaged one meshed with finite elements (FEM). This paper gives some details on the method implemented in the EUROPLEXUS code, its validation on simple benchmarks and a confrontation between numerical simulations and results of an experimental study of concrete slab resistance to projectile impacts.
