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 http://openfoam-extend.svn.sourceforge.net/svnroot/openfoam-extend/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 http://openfoam-extend.svn.sourceforge.net/svnroot/openfoam-extend/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
