Scour downstream of a sluice gate using SedFoam and FLOW-3D
Résumé
Sediment scour caused by a confined water wall jet downstream of a sluice gate is an interesting hydro-morphological phenomenon. The aim of this research is to simulate effectively this phenomenon using two different numerical models, SedFoam, a two-phase flow RANS model that use consecutive laws to perform direct coupling between the solid and liquid phase, and FLOW-3D Hydro a CFD software for multi-phase flow that has a built-in scouring model which is unlike SedFoam, doesn't use direct coupling. A data of a study on a scour downstream of a sluice gate due to a confined water jet by Martino et al. (2019) will be used as the reference to study this phenomenon. This will show the advantages and defaults of both models as well as reproduce numerically this phenomenon.
