Pressure Fluctuations in the S-Shaped Region of a Reversible Pump-Turbine

Pressure Fluctuations in the S-Shaped Region of a Reversible Pump-Turbine

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. Calculations were made under six different operating conditions wit...
