1 Mesh setup

The mesh was generated with ICEM-HEXA . The mesh is generated in four different parts (strout, stay vanes, runner and draft-tube), which can be seen in Figure 1.

Figure 1: the four different parts of the Timisoara Swirl Generator mesh.

This 2D mesh has 2703588 hexahedra cells. The four different parts are connected to each other with help of the GGI.

2 Running the case

This case is computed using four GGI interfaces: between the strout and the stay vanes, between the stay vanes and the runer, and between the runner and the draft tube.

Follow these steps to run the case from scratch:

First make sure that you have the following installed:

A recent revision of OpenFOAM-1.5-dev
A recent revision of the Breeder 1.5. In it you will find the libraries needed to use the turboPerformance and trackDictionary functionObject.

cd $FOAM_RUN/TimisoaraSwirlGenerator/TSG/
./Allrun &

To follow the simulation, the log.transientSimpleDyMFoam can be dumped on the screen and residuals can be plotted using the PyFoam utility.

To install PyFoam, please refer to PyFoam utility .

Useful command:

pyFoamPlotWatcher.py log.transientSimpleDyMFoam
