The course covers the use of OpenFOAM especially for the calculation of turbomachinery such as propellers, axial pumps or centrifugal pumps. In addition to the theoretical basics, best practice guidelines for the selection of numerical settings are taught. Another major topic is networking with open source tools. The knowledge is consolidated with examples.
