CFD-DEM Simulations of Seepage Induced Erosion
The increase of seepage force would reduce the effective stress of particles and result in the erosion of particles for the heave failure. The sheet piles/cutoff walls are often employed in the dams to control the seepage. In this paper, a solver of computation fluid dynamics (CFD) involving two-fluid phases is developed and coupled with the discrete element method (DEM) software for mimicking the piping process. The binary-sized particles are selected to study the impact of fine particles on the mechanisms of seepage. The results demonstrated that the developed software could successfully model the seepage process. It adopts the characteristics of particle displacements, drag force and porosity to illustrate the erosion mechanism. The results imply the seepage impact triggers the movement of particles in the downstream side with a looser condition for the skeleton, which resulting in the transportation of particles in the upstream side to achieve a flow channel.
