Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm ( Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brno, Austria-Hungary (now in the Czech Republic), obtained his first patent for an adjustable blade propeller turbine in 19 ...

S Vs Kaplan Schnitt 1 Zoom
S, or s, is the nineteenth letter of the Latin alphabet, used in the English alphabet, the alphabets of other western European languages and other latin alphabets worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a "sh" phoneme, so the derived Greek letter Sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''Samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ), "to hiss". The original name of the letter "Sigma" may have been ''san'', but due to the earl ...

Carbon Tax
A carbon tax is a tax levied on the carbon emissions from producing goods and services. Carbon taxes are intended to make visible the hidden Social cost of carbon, social costs of carbon emissions. They are designed to reduce greenhouse gas emissions by essentially increasing the price of fossil fuels. This both decreases demand for goods and services that produce high emissions and incentivizes making them less emission intensity, carbon-intensive. When a fossil fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to . Greenhouse gas emissions cause climate change. This negative externality can be reduced by taxing carbon content at any point in the product cycle. A carbon tax as well as carbon emission trading is used within the carbon price concept. Two common economic alternatives to carbon taxes are tradable permits with Carbon offsets and credits, carbon credits and Subsidy, subsidies. In its simplest form, a carbon tax covers only ...

Carbon Offsets And Credits
Carbon offsetting is a carbon trading mechanism that enables entities to compensate for offset greenhouse gas emissions by investing in projects that reduce, avoid, or remove emissions elsewhere. When an entity invests in a carbon offsetting program, it receives carbon credit or offset credit, which account for the net climate benefits that one entity brings to another. After certification by a government or independent certification body, credits can be traded between entities. One carbon credit represents a reduction, avoidance or removal of one metric tonne of carbon dioxide or its carbon dioxide-equivalent (CO2e). A variety of greenhouse gas reduction projects can qualify for offsets and credits depending on the scheme. Some include forestry projects that avoid logging and plant saplings, renewable energy projects such as wind farms, biomass energy, biogas digesters, hydroelectric dams, as well as energy efficiency projects. Further projects include carbon dioxide remo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banki Turbine
A cross-flow turbine, Bánki-Michell turbine, or Ossberger turbine''E.F. Lindsley,'' Water power for your homePopular Science, May 1977, Vol. 210, No. 5 87-93. is a water turbine developed by the Australian Anthony Michell, the Hungarian Donát Bánki and the German Fritz Ossberger. Michell obtained patents for his turbine design in 1903, and the manufacturing company Weymouth made it for many years. Ossberger's first patent was granted in 1933 ("Free Jet Turbine" 1922, Imperial Patent No. 361593 and the "Cross Flow Turbine" 1933, Imperial Patent No. 615445), and he manufactured this turbine as a standard product. Today, the company founded by Ossberger which bears his name is the leading manufacturer of this type of turbine. Unlike most water turbines, which have axial or radial flows, in a cross-flow turbine the water passes through the turbine transversely, or across the turbine blades. As with a water wheel, the water is admitted at the turbine's edge. After passing to the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyson Turbine
The Tyson turbine is a conical water turbine with helical blades emerging partway down from the apex gradually increasing in radial dimension and decreasing in pitch as they spiral towards the base of the cone. This design doesn't need a casement, as it is inserted directly into flowing water. Marketed as part of a hydropower system that extracts power from the flow of water, the turbine is mounted below a raft, driving a power system, typically a lift irrigation pump or generator, on top of the raft by belt or gear. The turbine is towed into the middle of a river or stream, where the flow is the fastest, and tied off to shore A coast (coastline, shoreline, seashore) is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape and by aquatic erosion, su .... It requires no local engineering, and can easily be moved to other locations.

La Grande-1 Generating Station
The La Grande-1 (LG-1) is a hydroelectric power station on the La Grande River that is part of Hydro-Québec's James Bay Project. The station can generate 1,436 MW and was commissioned in 1994–1995. A run of the river generating station, it is one of only two generating stations of the James Bay Project that use a reservoir without any major water-level fluctuations (the Laforge-2 generating station is the other). Thus, the amount of electricity generated by the station depends almost entirely on the water-flow of the river, which is largely controlled by upstream reservoirs and generating stations. __NOTOC__ See also * List of largest power stations in Canada * List of electrical generating stations in Quebec * Reservoirs and dams in Canada * Hydro-Québec * James Bay Project * Chisasibi, Quebec Chisasibi (; meaning Great River) is a village and Cree reserved land (TC) on the eastern shore of James Bay, in Eeyou Istchee, an equivalent territory (ET) in Nord-du ...

Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Wave Dragon
Wave Dragon is a concept wave energy converter of the overtopping type, developed by the Danish company Wave Dragon Aps. Incoming waves flow up a ramp into a reservoir, the water the drains back to sea level though a hydro-electric turbine, generating electricity. "Reflector arms" are used to focus incoming waves, to channel the waves towards the ramp, increasing the energy captured. In May 2003, it was the world's first offshore wave energy converter, connected to the Danish electricity grid. Testing continued in Denmark for several years until 2010. Plans were developed for a full-scale pre-commercial prototype in Wales, but this was never built. Part of the development of Wave Dragon was a joint EU research project, including partners from Austria, Denmark, Germany, Ireland, Portugal, Sweden, and the UK. History The concept was formulated in 1987, by Danish engineer Erik Friis-Madsen, and patented thereafter. Between 1998 and 2001, prototype testing of the device was condu ...

Computational Fluid Dynamics
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid dynamics, fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces defined by Boundary value problem#Boundary value conditions, boundary conditions. With high-speed supercomputers, better solutions can be achieved, and are often required to solve the largest and most complex problems. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulence, turbulent flows. Initial validation of such software is typically performed using experimental apparatus such as wind tunnels. In addition, previously performed Closed-form solution, analytical or Empirical research, empirical analysis of a particular problem can be used for compa ...
