# Two Dimensional Rising Bubble Benchmark (two cases)

From OpenFOAMWiki

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

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.
