Modelling mineral slurries using coupled discrete element method and smoothed particle hydrodynamics
TL;DR: In this paper, the non-Newtonian smoothed particle hydrodynamics (SPH) and its coupling to discrete element modeling (DEM) framework was initially described, and the results suggested that the SPH-DEM method should be used to more accurately model the slurry flows within grinding mills.

On the use of multibody dynamics techniques to simulate fluid dynamics and fluid–solid interaction problems
TL;DR: It is concluded that KCSPH is a robust alternative to conventional CFD approaches for fluid–solid interaction (FSI) problems with complex/moving boundaries by comparing its performance with the two most commonly used SPH algorithms in the CFD community: the weakly compressible SPH, and the implicit SPH (ISPH) methods.

Incompressible smoothed particle hydrodynamics-moving IRBFN method for viscous flow problems
TL;DR: In this article, a novel numerical approach based on incompressible smoothed particle hydrodynamics and moving integrated radial basis function networks method, namely ISPH-MIRBFN, was proposed for solving viscous flow problems, which reduces the spurious pressure fluctuations, yields a smoother pressure field solution and maintains the computational efficiency when compared to the ISPH.
