A Numerical Review of Multi-Fluid SPH Algorithms for High Density Ratios

authored by: Jan Philipp Fürstenau, Bircan Avci, Peter Wriggers
Abstract: The smoothed particle hydrodynamics (SPH) method is a recent numerical technique and particularly well suited for the simulation of free surface flows. The SPH method is also a good technique for the simulation of multi-fluid problems,as in that approach the fluid interface is resolved by freely moving particles. Due to high density gradients at the interface,the SPH multi-fluid models generally show instabilities for high density ratios. In the current work,the multifluid models of Monaghan and Rafiee [7],Colagrossi and Landrini [2],and Hu and Adams [6] are reviewed and benchmarked. The focus of this work is to survey the implementations with regard to stability,accuracy,and computational effort.
