Comparison of flow solvers for 3D two-phase flow simulations
We perform 3D incompressible two-phase flow simulations of rising droplets. Based on a similar 2D benchmark, a 3D benchmark configuration with two test cases is formulated in which we compare the flow solvers DROPS, NaSt3DGPF and OpenFOAM. All codes adopt different numerical techniques. We define several quantities of interest and investigate their temporal evolution in both test cases.

Benchmark specifications
To encourage other groups to participate in these benchmark simulations so that valid reference data for 3D two-phase flow solvers can be established, we make our data available on this website. If the provided simulation data is used for your further research, please cite the corresponding publication.
