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...

Diffuser Performance for Draft Tube Applications
Available information on diffuser performance is summarized in relation to draft tube applications. This paper is particularly directed at the implications of basic research with these...

Analysis and Testing of Transient Pressures at Camp Far West Hydroelectric Project
The objective of this paper is to present a comparative discussion of the results of theoretical analysis of transient pressures and of field tests performed on the Camp Far West Hydroelectric...

Hydraulic Machines Model Acceptance Tests
The article begins with a description of the modern test installations, giving the dimensions of the models most frequently used and the head heights. Attention is then given to the most...

Conventional Machinery/Unconventional Applications
The U. S. Bureau of Reclamation has become increasingly involved in small-scale hydroelectric projects involving unconventional applications for conventional hydraulic machinery. One ongoing...

An Overview of Hoover Dam Tunnel Spillway Damage
The Hoover Dam tunnel spillways have provided the Bureau of Reclamation hydraulic laboratories with new and continued opportunities for applied research. During the peak years of the Boulder...

Modernization of Existing Hydroelectric Power Stations in Conjunction with Conversion to Automatic Operation
The easiest and, in the long run, the least expensive method in most cases is the installation of an electronic turbine governor that is not only easy to incorporate in the power station...

Experiences During Overhaul of Hydroelectric Units
This paper describes some of the conditions found during major overhaul of main units at two hydroelectric power plants. Problems encountered and their solutions are described. The effects...

More Kilowatts with Less Investment
The paper discusses partial or complete modernization of hydraulic units and/or governing system as a means to increasing profitability. A combination of general and case history applications...

Analysis of Expanding the Wolf Creek Powerplant
The Nashville District, Corps of Engineers, is examining the feasibility of expanding the Wolf Creek powerplant to increase its peaking capability. The economic analysis of peaking expansions...

Application of Computer Aided Design and Analysis Tools for Upgrading Existing Power Plant Equipment
This paper presents examples where state-of-the-art computer aided design and analysis techniques have been applied to upgrade hydraulic performance and structural reliability of existing...

Synopsis: Ozark-Webbers Falls Turbine Repairs
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U. S. Army Corps of Engineers and are located on the McClellan-Kerr Arkansas River Navigation...

Competitive Model Testing for Replacement Runners at the Wells Hydroelectric Project
The Wells Hydroelectric Project, located on the Columbia River, contains ten Kaplan-type turbines. The plant has been in commercial operation since January, 1969. The runners have a long...

Application of an Integrated Numerical System for the Modernization of Hydro Turbines
The modules of an integrated numerical system for the new design and replacement of hydro power plant components are described and some examples of application are shown. The main modules...
