2 Published computational results
Auvinen et al. [1] has done a detailed analysis of this case, which forms the base of the case-study. Some of those results can be reproduced with these files.

4 How to get the files
Get all the current case files by doing:
cd $FOAM_RUN svn checkout svn://svn.code.sf.net/p/openfoam-extend/svn/trunk/Breeder_1.5/OSIG/TurboMachinery/singleChannelPump
In the descriptions below, we thus assume that the singleChannelPump directory is located in the $FOAM_RUN directory
Update your files every now and then by doing:
cd $FOAM_RUN/singleChannelPump svn update
See further info at OpenFOAM-extend webpage
You will also need the transientSimpleDyMFoam:
cd $FOAM_RUN svn checkout svn://svn.code.sf.net/p/openfoam-extend/svn/trunk/Breeder_1.5/OSIG/TurboMachinery/applications/solvers/incompressible/transientSimpleDyMFoam cd transientSimpleDyMFoam wmake
The turboPerformance functionObject is used to determine the shaft power, hydrodynamic head and efficiency. To install and use it, see Sig Turbomachinery Library turboPerformance
5 Directory structure
The case directory ($FOAM_RUN/singleChannelPump/Pump) contains the following files, scripts and directories:
README setBatch system/ constant/ Allclear Allrun.MRFSimpleFOAM Allrun.transientSimpleDyMFoam Orig.0/ transientSimpleDyMFoam.0/ transientSimpleDyMFoam.1/
Remember to look at the README file. It also contains information on how to run the cases.
6 Test cases
6.1 Descriptions of the scripts used in the cases
Allrun.MRFSimpleFoam: Perform steady-state MRFSimpleFoam analysis.
Allrun.transientSimpleDyMFoam: Perform time-accurate transientSimpleDyMFoam analysis.
Allclear: Remove time directories and return to the initial state.
