Numerical research of cavitation on Francis turbine runners
International Journal of Hydrogen Energy, 2017 Francis turbines, as other hydraulic turbines, are custom-designed for nominal operating conditions specific to each power plant. However, they may need to be operated at off design flow conditions because of variable reservoir levels and flowrates. Operating the turbine at off-design points can cause cavitation.

Toward the Development of a Uranium‐Based Redox‐Flow Battery
ChemSusChem, Volume 19, Issue 1, January 2026.The first all‐uranium‐based electrochemical cell has been realized using simple [UIV/V(tBuacac)4]0/+ and [UIII/IV(N(SiMe3)2)4]–/0 complexes, readily available in convenient, scalable syntheses, as anolyte and catholyte couples. Operating at a cell potential of 2.2 V with a projected energy density of 0.357 Wh kg–1, this system establishes a foundation ...

Influence of 3D Guide Vanes on the Channel Vortices in the Runner of a Francis Turbine
Journal of Fluid Science and Technology, 2006 It is known that the pressure fluctuation in the runner will become large when a Francis turbine operates at the low flow rate and high head. One of the reasons is the occurrence of channel vortices, which are caused by the three-dimensional flow ...
