sedFoam, a OpenFOAM solver for sediment transport

Abstract : Sediment transport is the main process that drives the morphological evolution of fluvial and coastal environments. Consequently, the ability to predict sediment transport is a major societal issue for the management of natural systems in order to limit and prevent the impacts related to extreme events exacerbated by climate change and human activities such as construction of hard structures (dams, harbors, dikes, etc.), land reclamation, and dredging. During the past two decades, an increasing amount of research efforts are devoted to develop two-phase flow models for sediment transport. In this two-phase flow approach, dynamical equations are solved for both the fluid phase (water) and the particle phase (sediment), with the latter being seen as a continuous phase dispersed in the fluid. The purpose of the present contribution is to follow up on [1] work by adding new capabilities to the open-source model sedFoam. In particular, the mixing length turbulence model and dense granular flow rheology used by [2] and [3] for sheet flows have been implemented. In addition, we implemented and tested the k − ω turbulence model for two- phase flow sediment transport modeling purposes. Our final goal is to provide a comprehensive numerical framework that solves the two-phase flow equations in three dimensions with the capability to select different combinations of turbulent model and granular stress model for sediment transport applications. By disseminating the numerical model in the open- source framework, in the long run, we expect new capabilities will be added to the model by the scientific community. We strongly believe that developing such an open-source community model is the only effective way to make significant progress.
