Files Preparation - Rotor Region
For creating new mesh using snappyHexMesh it is recommended to create new OpenFOAM test case just with system, constant and with empty directory 0. Go to your user directory and create directories for turbine rotor.
mkdir -p turbomachinery-CFD/meshFactory/as1/rotor
cp -r $WM_PROJECT_INST_DIR/Turbomachinery-CFD-XX.XX/
In this case, the interface between stator and rotor part is divided into the 36 radial strips (individual .STL files) to allow Mixing Plane averaging. (Compare to radial cases, where the rings were created on existing mesh using topoSet and createPatch). This approach was chosen just for practising purposes. Of course both approaches of creating Mixing Plane patches are possible. Following files will used:
The initial idea is to create following mesh boundaries:
Their number and names can change during the creation process.
