Evaluation of stability of Francis turbine Acceptance tests performed on a scale model in a hydraulic laboratory may provide the necessary informations for a full description of characteristics significant for the stability of operation of the full-size turbine in its piping system. Once the turbine is adequately described, the prediction of stability is performed using known methods and is done under responsibility of the technical consultant, as the prototype piping system layout is liable to change after the turbine model acceptance tests. Technical and economic consequences of a faulty stability of operation are such that the prediction of stability from model tests is one of the major challenges in present research on hydraulic machinery. lmhwww.epfl.ch /Services/ModelTesting/stabilitytest.htm   (665 words)

Harpers Ferry NHP Outward Flow Turbines In tests conducted by James B. Francis in 1845 and documented in the Lowell Hydraulic Experiments, the Boyden turbine was found to convert 88% of the energy available in the falling water into power. Fourneyron's patent described his invention as "a wheel of universal and continuous pressure or hydraulic turbine." This new turbine was put in operation in 1844, and became the pattern for the "improved Fourneyron or Outward Discharge Turbine Water-wheel" manufactured by E.C. Kilburn and Company, a Fall River textile machine shop. www.nps.gov /hafe/waterpwr/outward.htm   (647 words)

ADVANCED  CAR  INVENTION As the process goes "on line", the hydraulic accumulator operates mainly as a damper between the gas turbine and the engine crankshaft. Thus the pump of the power steering system starts to pump hydraulic liquid from the hydraulic tank through the non-return valves in the hydraulic accumulator and thus a part of kinetic energy of the car and/or engine is stored there. As power is needed, the engine computer management system opens the electric valves, and thus let the pressured liquid from the hydraulic accumulator to drive the pump as a hydraulic motor which on its side supplies additional power to the power train of the car. www.aci.dir.bg /Concept.htm   (768 words)

Waterpower The powerful hydraulic (water) turbine was developed in the mid-1800s. In this case, as in pumped-storage systems, the same machines alternate as pumps and turbines, but the head gained from the tide is used to reduce pumping power during high tide and to increase turbine output during low tide. Turbines are enclosed waterwheels designed to take full advantage of the pressure and velocity of water (see Turbine). www.geocities.com /CapeCanaveral/1706/waterpwr.html   (2094 words)

Mixed-flow turbines (from turbine) --  Britannica Concise Encyclopedia - The online encyclopedia you can trust! Francis turbines are probably used most extensively because of their wider range of suitable heads, characteristically from three to 600 metres. The first non-reversible Deriaz turbine, capable of producing 22,750 kilowatts with a head of 55 metres, was installed in an underground station at Culligran, Scot., in 1958. The powerful hydraulic (water) turbine was developed in the mid-1800s. www.britannica.com /ebc/article-45665?tocId=45665   (1453 words)

Lowell National Historical Park - Suffolk Mills Turbine Exhibit Francis' experiments on turbines led to the mixed-flow reaction turbine, which became the American standard. By contrast, turbines rotated as the falling water was conducted into them, striking the metal veins that spiraled around a central shaft. Francis continued experimenting with turbines, refining the design of an inward-flow turbine developed by an American named Samuel Howd in 1838. www.nps.gov /lowe/suffolk.htm   (1056 words)

The Steam Turbine, Part I gh, where h is the hydraulic head, gives the velocity of issue from a jet for steam with small heads and also for water, and I shall presently follow this part of the subject furgher in dealing with the design of turbines. I have said that steam behaves almost like an incompressible fluid in each turbine of the series, but because of its elasticity its volume gradually increases with the succession of small falls of pressure, and the succeeding turbines consequently are made larger and larger. The subject of our lecture today is the Steam Turbine, and it may be interesting to mention that the work was initially commenced because calculation showed that, from the known data, a successful steam turbine ought to be capable of construction. www.history.rochester.edu /steam/parsons/part1.html   (1071 words)

Hydraulic ram pump is a solution to water woes :: The Fence Post :: Celebrating Our Rural Lifestyle The hydraulic ram is made from 1 1/4-inch diameter schedule 40 PVC pipe and connections. Although commercial hydraulic ram pumps have been around for nearly 200 years, Thompson’s is a simple, inexpensive pump. But unlike a water wheel or turbine, the ram uses the inertia of moving water rather than water pressure, and operates in a cycle. www.thefencepost.com /article.php?sid=1126   (710 words)

Annex D - Turbine Passage Survival Program Results of various turbine performance model tests, funded outside of the scope of the TSP, have been incorporated into the hydraulic modeling at WES, as well as in developing the prototype test plans for the FY98 to FY99 engineering and biological field tests at McNary and Bonneville. The turbine blade angles, wicket gate angles, and turbine speeds for a given flow condition which were developed in the performance models were used in these models to simulate the prototype. Features which improved turbine efficiency and should reduce likely sources of turbine juvenile fish injury or mortality were included in the design and procurement of a replacement Kaplan turbine identified as a MGR has been undertaken. www.nww.usace.army.mil /lsr/final_fseis/study_kit/appendix_e/annex_d.htm   (9599 words)

Statement of Richard K. Fisher, Jr., Salmon Recovery on Columbia and Snake Rivers, Oct. 8, 1998 In testing the new auto-venting turbines, measurements are required to maximize the environmental and hydraulic performance of the aeration options. The number of turbine runner blades and stay vanes, the length of the fish compared to the size of the turbine, and the quality of the flow at the point of operation are key elements that characterize survival [12,16]. Modified Kaplan: Eliminating runner gaps, improved blade shapes and an advanced control system to sense the presence of fish are some modifications to a Kaplan turbine designed by the Voith Hydro, Inc. led team of engineers, biologists and university researchers that may increase survival rates to 98% according to one preliminary study. epw.senate.gov /105th/fis_10-8.htm   (4428 words)

Volt - Wikipedia, the free encyclopedia In a hydraulic system, the work done to move water is equal to the pressure multiplied by the volume of water moved. This hydraulic analogy (see separate article for full details) is a useful method of teaching a range of electrical concepts. If there is a pressure difference between two points, then water flowing from the first point to the second will be able to do work, such as driving a turbine. www.wikipedia.org /wiki/Voltage   (1090 words)
