We are pleased that the model test was successfully and on schedule completed at the beginning of January 2023. This was carried out in the laboratory of the Institute of Hydraulic Fluid Machinery at Graz University of Technology. The model test confirmed the demanding CFD design with regard to efficiency and especially cavitation.
