2D-3D COUPLING OF SHALLOW WATER EQUATIONS WITH REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS

A full bi-directional coupling of 2D Shallow Water with 3D Reynolds-averaged Navier- Stokes equations, in the framework of the Open Source CFD code OpenFOAM is presented. A Dirichlet-Neumann coupling, based on an exchange of values and fluxes at the 2D-3D interface, is employed. Results of unsteady test cases are presented.
