Adaptive Turbine Replacement Improves Hydropower Flexibility in a Changing Climate

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Hydropower plants will operate under new conditions as water regimes shift, reservoir operating rules evolve, and the grid requires flexible balancing of wind and solar. Hydropower plant turbine systems are traditionally designed to operate at the highest efficiency within narrow ranges of flow and reservoir levels while deviations from design

A Rortex-based method for evaluating hydraulic losses in pump-turbines: a case study of turbine mode under different load conditions

Engineering Applications of Computational Fluid Mechanics
When pump-turbines operate under off-design conditions, complex internal vortex flows often arise, leading to hydraulic instabilities and increased energy losses. Traditional hydraulic loss evaluation methods fail to quantitatively link vortex structures

Flow characteristics of curved ducts [PDF]

Applied and Computational Mechanics, 2007
Curved channels are very often present in real hydraulic systems, e.g. curved diffusers of hydraulic turbines, S-shaped bulb turbines, fittings, etc. Curvature brings change of velocity profile, generation of vortices and production of hydraulic losses ...
