3D numerical modeling of flows on a reduced model of a ski jump spillway with an erosion pit using a coupled SPH–FEM-DEM approach

Abstract

Plunge pools are an economical means for discharging energy flows downstream of dams. However, the high energy discharge usually falls down from a considerable height, which leads to the phenomenon of erosion. The understanding of this risk is of paramount importance. In this study, a numerical modeling using a coupled SPH-FEM-DEM method was developed to simulate the hydraulic behavior of a physical model Ski-Jump Spillway. Several examples of validation demonstrate the precision of developed models.
