In collaboration with the Institute for Energy Systems and Thermodynamic

Numerical flow simulations via the open source software OpenFOAM are used to establish the lifetime of hydraulic turbine runners by determining compression forces.

To establish the lifetime of hydraulic turbine runners, numerical flow simulations are conducted via the open source software OpenFOAM to determine the occurring compression forces. The recorded data is then used for a finite element analysis with the freely available program Code_Aster.

To minimize the duration of FE-Simulations, the cyclical symmetry of the impeller geometry is utilized to reduce the size of the model. This however requires consideration of periodic edge conditions of the cut surface of the reduced model. Code_Aster currently only has limited functionality in this regard.

During the course of this project, these cyclical/periodic edge conditions should be implemented into Code_Aster and validated by means of test examples of parts of the model as well as the model as a whole.
