1 Special Interest Group on Multiphase Flows in OpenFOAM

The German Special Interest Group on Multiphase Flows in OpenFOAM® was initiated at the Southern German user meeting "OpenFOAM® Stammtisch" in 2009.

Responsibles: Kathrin Kissling (University of Stuttgart) and Holger Marschall (Technical University of Munich).

Special Interest Group on extend-project.de: Multiphase Flows

Please note: This offering is not approved or endorsed by OpenCFD® Limited, the producer of OpenFOAM® software and owner of the OpenFOAM® and OpenCFD® trademarks.

2 Objectives

  • Identify common interests with OpenFOAM® for the different multiphase flow types, and plan joint activities.
  • Develop OpenFOAM® for multiphase applications, including pre-processing, solution methods, and post-processing.
  • Provide tutorials on how to produce accurate results using OpenFOAM® for multiphase flows.
  • Distribute relevant validation test cases and corresponding OpenFOAM® applications.
  • Use OpenFOAM® to develop Best Practice Guidelines for CFD for multiphase flows.
  • Connect people with the same interest: OpenFOAM® and multiphase flows.
  • Organize meetings, workshops and collaborations.

3 Guidelines

Source files and tutorial cases should be located in the OpenFOAM extensions on SourceForge.net under the SVN repository.

Detailed written reports and tutorials should be added to the workspaces below.

4 Work space for Tutorials

Please provide some additional tutorials along with some description in order to give a first help for new FOAMers!


4.1 Tutorials for particle based methods

The tutorials for particle based methods have moved to its own Wiki page.

5 Work space for Reports and Validation

For a comprehensive validation database for free-surface flows have a look into the OpenFOAM® extensions on SourceForge.net under the SVN repository. You will find

  • Advection Tests (Cylinder in Vortex Flow, Zaleski's Disc)
  • Spurious Currents (Droplet under zero-gravity conditions)
  • Surface Tension Implementation (Oscillating Droplet)
  • Overall Performance I (Dambreak Tests (with and without obstacle))
  • Overall Performance II (Rising Bubble)
  • Overall Performance III (Sloshing Tank (will be added soon))

Please find below a LaTeX template for typesetting technical reports describing the validation of OpenFOAM®'s top-level multiphase solvers. The template holds both FOAM-specific macros for finite volume and FOAM-specific macros for tensor notation in LaTeX in order to provide a reasonable basis for reports that provide detailed and comprehensive information on validation test cases for multiphase flows.

If you are interested in working with us on the field of Multiphase Flows within the Special Interest Group, please download the provided report template / specific reports and complete or correct them where appropriate; add yourself to the list of authors and upload the new report version to this page. Please have a close look at the provided packages and macros, i.e. the pgfplots package enables any user of the above test cases to provide the original validation data (numerical values) to the community for re-use along with a illustrative plot within the report.

6 Current projects

  • Creation of a comprehensive validation database for free-surface flows (see above)
  • Creation of a comprehensive validation database for particle flows (planned)
  • Work on specific projects
  • Organize the next meeting
