Hysing et. al <ref>Hysing, S.; Turek, S.; Kuzmin, D.; Parolini, N.; Burman, E.; Ganesan, S.; Tobiska, L.: Quantitative benchmark computations of two-dimensional bubble dynamics, International Journal for Numerical Methods in Fluids, Volume 60 Issue 11, Pages 1259-1288, DOI: 10.1002/fld.1934, 2009, [http://onlinelibrary.wiley.com/doi/10.1002/fld.1934/abstract]
</ref> published 2009 a pure numerical benchmark with two test cases for a 2D rising bubble. The reference data can be downloaded here [http://www.featflow.de/en/benchmarks/cfdbenchmarking/bubble.html].
The boundary conditions are visualized in the following picture: [[Image:KlostermannEtAl_TestCases.png|c|center|Initial and boundary conditions]]

The two test case are distinguished by the material properties resulting in two different non-dimensional groups see table with material properties:

The test cases and solver as used in <ref>Klostermann, J.; Schaake, K.; Schwarze, R.: Numerical simulation of a single rising bubble by VOF with surface compression, International Journal for Numerical Methods in Fluids, Article first published online: 16 JUL 2012, DOI: 10.1002/fld.3692 [http://onlinelibrary.wiley.com/doi/10.1002/fld.3692/abstract]
</ref>:[[Media:TestCasesAndSolver.zip]] eventually rename the variable gamma to alpha1 (both in the test cases and the solver) depending on the version of OF you are using.
