An Integrated Flow Analysis System for the Recalculation of Hydraulic Machinery Bladings

open access: yesInternational Journal of Rotating Machinery, 1996
The present paper deals with the recalculation of hydraulic machinery bladings. By combining numerical tools for the geometrical description of the bladings, mesh generation, different CFD flow models (Q3D Euler, 3D Euler, Navier-Stokes) and post ...

Hydraulic Power and Hydraulic Machinery [PDF]

open access: yesNature, 1887
THIS work purports to “record existing experience in this branch of engineering.” It is divided into thirty-five short chapters (not numbered, and therefore not quite easy of reference). Five of these treat of general subjects, and the rest of particular machines or details. Hydraulic Power and Hydraulic Machinery. By H. Robinson, M.I.C.E., &c. Pp. xiv.

Dynamic Analyses of the Hydro-Turbine Generator Shafting System Considering the Hydraulic Instability

open access: yesEnergies, 2018
Hydraulic instability is a complex factor causing the vibration of hydro-turbine generator shafting system (HGSS), and the mechanism is the uneven distribution of flow along the circumference.

A superelement-based method for computing unsteady three-dimensional potential flows in hydraulic turbomachines [PDF]

open access: yes, 1999
A numerical method is presented for the computation of unsteady, three-dimensional potential flows in hydraulic pumps and turbines. The superelement method has been extended in order to eliminate slave degrees of freedom not only from the governing ...
