The present work is dedicated to a weakly-compressible multi-fluid SPH model where a diffusive operator is used in the Volumetric Strain Rate equation in order to remove instabilities from the pressure field. The present model is obtained through a combination of other exiting models [1]- [6]. The new proposed scheme is validated through numerous well-known benchmarks showing that we are able to recover the results already present in the literature but improving the solution of the pressure field.

Abstract

The present work is dedicated to a weakly-compressible multi-fluid SPH model where a diffusive operator is used in the Volumetric Strain Rate equation in order to remove instabilities from the pressure field. The present model is obtained through a combination of other exiting models [1]- [6]. The new proposed scheme is validated through numerous well-known benchmarks showing that we are able to recover the results already present in the literature but improving the solution of the pressure field.
