SUMMARY Sloshing of liquid–solid particle mixtures is an important issue in industrial settings and research fields. In numerical simulations, difficulties are encountered in capturing or tracking the interface between different phases and calculating the interactions between particles, as well as considering hydrodynamic effects between liquid and particles. The finite volume particle (FVP) method, which is based on the Lagrangian framework, does not require applying extra techniques to capture the dynamics at the interface. Moreover, the hydrodynamic behavior between liquid phase and solid particles can be solved implicitly. The discrete element method (DEM) is a useful computational tool, which can explicitly calculate the interaction forces acting on particles and exactly describe their transient trajectories. Owing to the same particle assumption and Lagrangian description, the approach coupling FVP and DEM is more straightforward than the Euler–Lagrange approach. In this study, the applicability of the coupled FVP/DEM method is investigated by simulating sloshing in liquid–solid particle mixtures. A comparison of simulation and experimental results shows good agreement and demonstrates the accuracy of the method. It is hoped that the FVP/DEM method can provide an effective 3D means for a quantitative comparison and validation of more complicated multiphase flows with a variety of particles.
