1 About

A three-dimensional two-phase flow solver, SedFoam, is presented for sediment transport applications. The solver is based on twoPhaseEulerFoam available in the 2.1.0 release of the open-source CFD software OpenFOAM. In this approach the sediment phase is modelled as a continuum, and constitutive laws have to be prescribed for the sediment stresses. In the proposed solver, two different inter-granular stress models are implemented: the kinetic theory of granular flows and the dense granular flow rheology $(I)$. For the fluid stress, laminar or turbulent flow regimes can be simulated and three different turbulence models are available for sediment transport: a simple mixing length model (one-dimensional configuration only), a $k-$ and a $k-$ model. The numerical implementation is first demonstrated by two validation test cases, sedimentation of suspension and laminar bed-load, and two applications are then shown to illustrate the capabilities of to deal with complex turbulent sediment transport problems. Different combinations of inter-granular stress and turbulence models are tested. The source code and tutorial cases are disseminated at the public website: http://github.com/sedfoam/sedfoam and detailed tutorial description and documentation can be found at http://servforge.legi.grenoble-inp.fr/pub/soft-sedfoam/.

2 References and Citing

If you want to reference the model in your publications it should be called SedFoam, and state that is an evolution of twoPhaseEulerFoam, referencing any of the following research papers, in which the SedFoam implementation, validation and application details are published:

3 Downloading

For 5.0 OpenFOAM (or version 6 or OpenFOAM Plus version 1806), Download the official SedFoam-3.0 package:

git clone http://github.org/sedfoam/sedfoam/

For 2.4.0 OpenFOAM, you can use the old version (SedFoam-2.0) : https://github.com/SedFoam/sedfoam/releases/tag/v2.0

4 Building

This is a short overview of the installation process. A more detailed description is found here (consult these pages if you have problems during installation)


In the directory of the sources just do

./Allwmake

and everything should be built.

Please note that for OpenFOAM 6, you must comment and uncomment one line in sedFOAM.C (search 6 in file)
