DOI: 10.3390/en10010096
Abstract: Numerical simulations were performed to investigate pressure fluctuations in the S-shaped region of a pump-turbine model. Analyses focused on pressure fluctuations in the draft tube and in the gap between the guide vanes and runner.… read more here.

DOI: 10.5293/ijfms.2017.10.3.287
Abstract: The most detrimental pressure pulsations in high-head pump-turbines is caused by the rotor–stator interaction (RSI) between the guide vanes and runner blades. When the pump-turbine operates in the S-shaped region of the characteristic curves, the… read more here.
