Simulation of the Single Bubble Ascent with OpenFOAM

Lutz Böhm, Markus Kolano, Matthias Kraume


This project is motivated by the challenge of cleaning flat sheet membrane surfaces with the help of aeration. On the basis of earlier experiments and CFD simulations, a decision was made to use the CFD-tool OpenFOAM in contrast to earlier simulations which were performed with Ansys Fluent. In the new simulations, the advancing computing power allowed the simulation of a bubble ascent in the full channel which is of special interest in cases where the bubble size is smaller than the channel depths. Besides saving the licensing cost, OpenFOAM allows access to the source code and, therefore, easier implementation of sub-models if necessary.
