CFD-DEM Simulations of Seepage Induced Erosion [PDF]
Water, 2020 Increases in seepage force reduce the effective stress of particles and result in the erosion of particles, producing heave failure and piping. Sheet piles/cutoff walls are often employed in dams to control the seepage. In this study, a computational fluid dynamics solver involving two fluid phases was developed and coupled with discrete element method

Toward High-Order CFD-DEM: Development and Validation
Industrial & Engineering Chemistry Research, 2023 CFD-DEM is used to simulate solid-fluid systems. DEM models the motion of discrete particles while CFD models the fluid phase. Coupling both necessitates the calculation of the void fraction and the solid-fluid forces resulting in a computationally expensive method.
