Dynamics of Runner and Shafting Vibration Characteristics in a Pump-Turbine Under the Influence of Draft Tube Vortex Rope
To investigate the dynamic transmission of unsteady hydraulic excitation within pumped-storage units, this study presents a numerical investigation on the three-dimensional shafting vibrations of a pump-turbine based on a one-way transient fluid-structure interaction approach. To resolve the flow field, we adopt the sh...
