Numerical modelling of erosion in rock spillway channels

| 2023:981 | PENGHUA TENG, FREDRIK JOHANSSON, GUNNAR HELLSTRÖM
In this project, a coupled CFD-DEM approach has been employed to reproduce the rock erosion process observed in a previously conducted physical experiment of the erosion of a single rock block.

\u003Cp\u003EThe results show that the CFD-DEM successfully can be used to model the erosion process, and it could also provide a reference to determine the threshold for initiation of the process. As a result, the CFD-DEM may constitute an important future tool for rock erosion assessment.\u003C/p\u003E
