Hydraulic Turbine Setting Criteria

Journal of Engineering for Power, 1965
Higher settings of hydraulic turbines are proposed which will result in lower relative tailwater levels with associated operational improvements. Present selling criteria may lead to unsatisfactory operation at higher tailwater levels. Cavitation damage is not necessarily prevented by low settings, and draft-tube surges may occur under high tailwater ...

A new bladeless hydraulic turbine

Applied Energy, 2013
A water turbine constructed on the water turbulence or whirlpool principle is capable of utilizing very small sources even for untapped water, and it is highly suitable for the closed circuit production of electrical energy. The non-monotonic distribution of the radial velocity component is important for the onset of the driving force of the angular ...

Hydraulic-Turbine Runner Vibration

Journal of Fluids Engineering, 1956
Abstract This paper describes an investigation of the vibration characteristics of Francis-turbine runners and some experiments to determine the influence of different shapes of runner-bucket discharge edges on the excitation forces. Modifications suggested by the experiments were made to field runners and were successful in eliminating ...

Measurement of Hydraulic-Turbine Vibration

Journal of Fluids Engineering, 1952
Abstract This paper describes a test program used to measure and eliminate the vibration which had produced extensive cracking in the blading of a slow-speed, 40,000-hp hydraulic turbine. Strains, accelerations, and pressures were measured at various locations on the turbine runner while the unit was in operation.
