Two Dimensional Rising Bubble Benchmark (two cases)
From OpenFOAMWiki
1 The benchmark of Hysing et. al
Hysing et. al published 2009 a pure numerical benchmark with two test cases for a 2D rising bubble. The reference data can be downloaded here [1].
The boundary conditions are visualized in the following picture:
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 [3]: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.
