Abstract: This article describes the application of 'stage capability' in CFD for industrial turbomachinery flow simulations. The method of coupling stationary and rotating components together in one simultaneous steady-state calculation for complete turbomachines is presented and different applications are shown. For a Francis turbine of high specific speed details of the CFD results are discussed and compared to experimental data. Very good agreement between the numerical prediction and the experimental data can be seen. The advantages of coupled stage simulations for turbomachinery design and analysis are discussed.
