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...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
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...
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...
Advance Prediction of Flow-Induced Variations
Frequency analysis of hydraulic vibrations has been applied using a transfer matrix and impedance method. The computer program is given for the self-excited and forced vibrations, together...
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...
