D Puga, C Geng, Z Wang, X Luo - Physics of Fluids, 2025 - pubs.aip.org
A self-induced instability known as vortex rope enhanced by cavitation usually occurs at part
load operation conditions in the draft tube and negatively affects the normal operation of …

Optimal flow control of vortex breakdown in a laminar swirling flow

Z Seifi, M Raisee, MJ Cervantes - Journal of Physics: Conference …, 2024 - iopscience.iop.org
In highly swirling flows, such as hydraulic turbines operating under part-load (PL) conditions,
vortex breakdown occurs and performance is impaired. Consequently, it is imperative that …
