The paper discusses a system for producing custom designed turbines which are attractive in price and delivery, retaining the advantages of customization. A computerized program is being...
Small Kaplan Versus Tubular and Francis Turbines
Mossefossen Power Plant is situated in the centre of the small town Moss in the southern part of Norway. Water flows from an existing dam through a 9 m**2, 175m long tunnel to the powerhouse...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Hydroturbine Intake and Penstock Geometry Design
This paper studies the intake design of one hydroturbine site and the penstock trifurcation design of another site. A hydroturbine site had been built and was in operation when vortexing...
Interchangeable Runners Can Increase Energy Output
Interchangeable turbine runners can be used to increase energy generation at some hydroelectric power sites. Two different turbine runners can be designed for different design heads or...
The Design, Analysis and Manufacturing of Pickwick Landing Replacement Runners
This paper presents new computer automated techniques for the design, analysis and manufacture of Kaplan turbine blades. The inlet flow field was determined using the finite element program...
Design and Manufacture of Turbine Runner Blades Using CAD/CAM-Technology
Interactive blade design, fluid flow analysis, stress analysis and NC-matching of both model and prototype blades are working from a common data base and are demonstrated in this paper....
Computerized Engineering for the Hydraulic Design of Hydro-Turbine Stay Vanes
To design a turbine stay vane as an integral part of the spiral case/stay vane/wicket gate waterpassage, both the vane geometry and the gate/vane position must be developed and analyzed....
Analyses and Field Tests for Hydraulic Transients Sultan Hydroelectric Project
Two in-line Francis units with their long discharge conduit and bypass valves present some unique problems in controlling hydraulic transients in this system. The problems were compounded...
Open Flume Turbine Intake Geometry
An inexpensive physical hydraulic model was used to investigate the geometry of two different open flume turbine intakes. One intake utilized an inverted, fabricated pump bell type of...
