This paper mainly summarizes the recent progresses for the cavitation study in the hydraulic
machinery including turbo-pumps, hydro turbines, etc.. Especially, the newly developed …

Abstract Design and performance analysis of hydraulic turbines are two very crucial aspects
of any hydro power project which ensure economical and efficient functioning of these …

In the plain river network area, the constructed axial-flow pumping station is used to
generate electricity by reversing as turbine when the upstream water is abundant, which can …

A grid-connected integrated system incorporating cascade hydropower, solar/photovoltaic,
and wind power requires a hydraulic turbine to operate frequently under off-design …

Abstract Rotating Vortex Rope (RVR) has been a matter of focus for years due to the major
effects on hydraulic turbine's efficiency. The exact procedure of RVR formation is still vague …

When a Francis turbine operates over an extended range of regimes far from the best
efficiency point, the formation of a helical precessing vortex rope can lead to reduced …

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

Precessing vortex rope (PVR) plays a key role in inducing hydraulic resonance in Francis
turbines operating at partial load, possibly degrading power plant stability and availability …

This review addresses the current state of research into active control and suppression of
vortex rope in hydroturbines under off-design operating conditions. Only active control …

Abstract Development of rotating vortex rope (RVR) at part load (PL) operation is a source of
pressure fluctuations in draft tube and power swings, which may lead to runner failure under …
