Numerical simulation of pressure pulsation in vane area of a pump-turbine at pump mode [PDF]

open access: yes, 2020
When a reversible pump-turbine is running under the low-flow conditions in pump mode, it is easy to produce low-frequency and high-amplitude pressure pulsation, which affects the stability of the unit.
