Characterization of Pressure Pulsation Propagation in a Pump‐Turbine Based on the Same‐Frequency Tracking Method

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Pressure pulsation is a key factor affecting the safe and stable operation of pump‐turbines. This article is based on same frequency‐tracking method on the pressure pulsation propagation characteristics of pump‐turbine during generation mode. The numerical simulation is validated by experimental study on a model pump‐turbine.
