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.
