Investigation of the Sloshing Behavior Due to Seismic Excitations Considering Two-Way Coupling of the Fluid and the Structure

Abstract: Sloshing behavior due to near-fault type and earthquake excitations of a fluid in a tank having a highly deformable elastic structure in the middle was investigated experimentally and numerically in this paper. In the numerical model, fluid was simulated with smoothed particle hydrodynamics (SPH) and structure was simulated with the finite element method (FEM). The coupling was satisfied with contact mechanics. The δ-SPH scheme was adapted to lower the numerical oscillations. The proposed fluid-structure inter… Show more

“…At T = 2.5 s, the crest of the tailings flood moves back toward the tailings pond (Figure 4f). This phenomenon is well-known as sloshing [93,94]. Finally, one notes that the tailings particles near the rigid back walls of the tailings pond always show delayed movement, probably due to the friction and viscosity along the tailings-wall interfaces (see Figure 4b,c,f).…”

“…It is important to emphasize that in enhancing the site selection process, it is prudent to refine the chosen locations by incorporating natural hazard assessments. This can be achieved through the application of numerical methods [55][56][57], which specifically focus on seismic activities. Additionally, considerations should extend to factors such as erosion and flood risks [37], as well as potential landslides and debris flows [58].…”

“…Due to the Lagrangian nature, SPH has the advantage in simulating strongly nonlinear and discontinuous phenomena compared with traditional grid-based approaches. In recent years, many researchers have applied the SPH method to the simulation of strongly nonlinear free-surface flows, such as dam-breaking, multi-phase flow and liquid sloshing [5][6][7][8][9][10][11][12][13], because the SPH method does not need to track the free surface, which is usually a quite complicated problem for grid-based methods and numerical errors can easily be introduced [14,15].…”
