1 The benchmark of Hysing et. al

Hysing et. al [1] published 2009 a pure numerical benchmark with two test cases for a 2D rising bubble. The reference data can be downloaded here [3].

The boundary conditions are visualized in the following picture:
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 material properties of the two test cases
Case ρ1 ρ2 μ1 μ2 g σ Re Eo Ca
TC1 1000 100 10 1 0.98 24.5 35 10 0.286
TC2 1000 1 10 0.1 0.98 1.96 35 125 3.571


The test cases and solver as used in [2]: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.
