Electricity generation from solar and wind has raised a significant concern about the stability
of grid networks. Hydroelectricity plays an important role to balance the stability of grid …

In the high-head reversible pump-turbines, the most unfavourable hydraulic instability is the
unstable pressure fluctuations in the vaneless space caused by interactions between the …

Pump-as-turbine stations with ultra-low head often face the deterioration risk during load
rejection operations when the demands in water delivery and power generation are …

For most of low-head pump stations, pumps simultaneously undertake important tasks such
as flood control, irrigation and drainage where more attention should be paid on involved …

In order to explore the impact load and instantaneous fluid pressure of transient flow on
pump station system under the nonregulative operating conditions, the transient …

Over the past decade, the use of conventional one-dimensional numerical-simulation
methods has been demonstrated to be inadequate in terms of their usefulness in …

This study aimed to analyze the time–frequency characteristics of pressure fluctuations and
reveal their underlying flow mechanisms during the unavoidable guide vane closing process …

Applications of computational fluid dynamic (CFD) techniques to hydropower have
increased rapidly in the last three decades. The majority of the experimental investigations …

Due to the massive entrance of new renewable energies such as wind or solar, hydraulic
turbines have to work far from its designed point and withstanding multiple transients, such …

Hydraulic turbines include stationary and rotating components. The interaction of the
components, mainly between the runner blades and distributor vanes, is critical when the …
