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 …

If large pressure fluctuation is observed in the draft tube of a Francis turbine at part-load
operation, we have generally called it draft-tube-surge. As occurrence of this phenomenon …

The large eddy simulation model coupled with the modified Schnerr–Sauer cavitation model
has been used to numerically simulate the unsteady cavitation and noncavitation flow of the …

Compared to non-cavitating flow, cavitating flow is much complex owing to the numerical
difficulties caused by cavity generation and collapse. In this paper, the cavitating flow around …

The cavitating flow around the asymmetric leading edge (ALE) 15 hydrofoil is investigated
through large eddy simulation with the modified Schnerr–Sauer cavitation model, which …

Inter-blade vortex refers to a specific type vortex cavitation observed in Francis turbines
under partial loads and its adverse impact is widely recognized as a crucial factor that limits …

The waterjet pump is widely applied in the high-speed marine vessels to exploit various
kinds of resources in the vast ocean. The transient cavitating flows in a waterjet pump are …

Hydropower plants play an important regulatory role in the large scale integration of volatile
renewable energy sources into the existing power grid. This duty however requires a …

The objective of this paper is to investigate the two-phase flow structure of cloud cavitation
over a flexible hydrofoil with particular emphasis on cavitating flow-induced vibration and the …

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