Illustration Explanation Presentation

The purpose of the illustration is to display the functional parts of a wind turbine

inside and out. The illustration shows the inside of a wind turbine. The illustration shows

the gears inside a wind turbine used to generate sustainable electricity. The turbine is

sustained through battery power to keep the blades spinning and located inside the main

body of the turbine is a system of gears that make the mechanism work, so that the wind

mill will spin and stay perpetual through a combination of wind power and battery

operation.

The illustration is important to those interested in wind power, sustainable energy

and anyone interested in physics. Wind turbines are not the primary source of electricity in

most of the world. They are a choice alternative nuclear power. The illustration may be

interesting to people in the field of engineering, people with an interest in the environment,

such as activists or anyone with an interest in mechanics.

The wind turbine is important because we need better sources of renewable energy

in the United States as well as other first world nation, though there is already allot of wind

turbines in a few third world nation we, activists have not been able to establish a strong

foundation to develop renewable wind power here in the United States, Iran and most of

Europe were nuclear power is abundant.

Wind is among the most efficient renewable energy (http://www.gereports.com/going-dutch/) sources.

Still, there’s always room for improvement, and researchers are always trying to increase the power

output of wind turbines. Now, researchers at GE Global Research are analyzing ways to boost wind

turbine productivity by 2 percent. Given that 240GW of new wind installations is projected globally

over the next five years, a two percent increase would create 5GW of additional wind power capacity.

That’s enough to power every household in New York City, Boston, and Los Angeles, combined.

A limiting factor in developing more powerful wind turbines is noise. GE’s wind blades do not pose

noise issues today (http://www.gereports.com/how-loud-is-a-wind-turbine/). Researchers ensure this

by measuring noise levels of blade sections in wind tunnels and of entire wind turbines in the field.

One approach to boost the power output is to spin the rotors faster, but this also pushes the noise

levels of the turbine beyond allowable limits. However, notes Giridhar Jothiprasad, a mechanical

engineer with GE Global Research, “If you change the blade design to be quieter, you can spin the

rotor faster to produce more power and still meet noise regulation standards.”

Stanford University)

High fidelity computer simulations enable the design of low noise blades by providing better insights

into noise sources and noise generation mechanisms. That’s why the GE researchers partnered with

Stanford University and Sandia National Laboratory in New Mexico, home to the Red Mesa, one of

the world’s fastest and most energy-efficient supercomputers (https://share.sandia.gov

/news/resources/news_releases/oracle-award/#.Ugy0mlp4ZNs). The Red Mesa at Sandia is

dedicated to alternative energy modeling projects that would take months or years to complete

without its power.

“Sandia and other DOE national laboratories are using high-performance computing resources to

tackle complex design problems in wind energy, such as reducing turbine blade noise to achieve

significant reductions in cost-of-energy,” says Matt Barone, of Sandia’s Aerosciences Department,

formerly of the Wind Energy Technologies Department.

Keep it Down: Sleeker wind turbine blades could produce more energy without producing more

noise.

To reduce the noise on the turbine blade, the researchers had to know where it was coming from.

They ran high-fidelity Large Eddy Simulation (LES) code, developed at Stanford University, to predict

the detailed fluid phenomena and resulting wind blade noise. The simulation ran continuously over a

period of three months on the supercomputer.

“Having access to Sandia’s supercomputer was invaluable in our ability to conduct these

experiments and make discoveries that will bolster wind power’s potential,” says Mark Jonkhof, Wind

Technology Platform Leader at GE Global Research.

“By using high-performance computing to advance current engineering models that are used to

predict blade noise, we can build quieter rotors with greater blade tip velocity that produce more

power”, says Jonkhof. “This not only means lower energy costs for consumers, but also a significant

reduction in greenhouse gas emissions.”

From Wikipedia, the free encyclopediaJump to: navigation, searchFor other uses, see Turbine (disambiguation).A steam turbine with the case opened

A turbine, from the Greek "τύρβη" ("turbulance"), is a rotary mechanical device that extracts energy from afluid flow and converts it into useful work. A turbine is a turbomachine with at least one moving part called arotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that theymove and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels.

Gas, steam, and water turbines usually have a casing around the blades that contains and controls the workingfluid. Credit for invention of the steam turbine is given both to the British engineer Sir Charles Parsons(1854–1931), for invention of the reaction turbine and to Swedish engineer Gustaf de Laval (1845–1913), forinvention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in thesame unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

The word "turbine" was coined in 1822 by the French mining engineer Claude Burdin from the Latin turbo, orvortex, in a memoir, "Des turbines hydrauliques ou machines rotatoires à grande vitesse", which he submitted

to the Académie royale des sciences in Paris.[1] Benoit Fourneyron, a former student of Claude Burdin, builtthe first practical water turbine.

Schematic of impulse and reaction turbines, where therotor is the rotating part, and the stator is thestationary part of the machine.

A working fluid contains potential energy (pressure head) and kinetic energy (velocity head). The fluid may becompressible or incompressible. Several physical principles are employed by turbines to collect this energy:

Impulse turbines change the direction of flow of a high velocity fluid or gas jet. The resulting impulse spins theturbine and leaves the fluid flow with diminished kinetic energy. There is no pressure change of the fluid orgas in the turbine blades (the moving blades), as in the case of a steam or gas turbine, all the pressure droptakes place in the stationary blades (the nozzles). Before reaching the turbine, the fluid's pressure head ischanged to velocity head by accelerating the fluid with a nozzle. Pelton wheels and de Laval turbines use thisprocess exclusively. Impulse turbines do not require a pressure casement around the rotor since the fluid jet is

created by the nozzle prior to reaching the blading on the rotor. Newton's second law describes the transfer ofenergy for impulse turbines.

Reaction turbines develop torque by reacting to the gas or fluid's pressure or mass. The pressure of the gas orfluid changes as it passes through the turbine rotor blades. A pressure casement is needed to contain theworking fluid as it acts on the turbine stage(s) or the turbine must be fully immersed in the fluid flow (such aswith wind turbines). The casing contains and directs the working fluid and, for water turbines, maintains thesuction imparted by the draft tube. Francis turbines and most steam turbines use this concept. Forcompressible working fluids, multiple turbine stages are usually used to harness the expanding gas efficiently.Newton's third law describes the transfer of energy for reaction turbines.

In the case of steam turbines, such as would be used for marine applications or for land-based electricitygeneration, a Parsons type reaction turbine would require approximately double the number of blade rows as ade Laval type impulse turbine, for the same degree of thermal energy conversion. Whilst this makes theParsons turbine much longer and heavier, the overall efficiency of a reaction turbine is slightly higher than theequivalent impulse turbine for the same thermal energy conversion.

In practice, modern turbine designs use both reaction and impulse concepts to varying degrees wheneverpossible. Wind turbines use an airfoil to generate a reaction lift from the moving fluid and impart it to therotor. Wind turbines also gain some energy from the impulse of the wind, by deflecting it at an angle.Crossflow turbines are designed as an impulse machine, with a nozzle, but in low head applications maintainsome efficiency through reaction, like a traditional water wheel. Turbines with multiple stages may utilizeeither reaction or impulse blading at high pressure. Steam turbines were traditionally more impulse butcontinue to move towards reaction designs similar to those used in gas turbines. At low pressure the operatingfluid medium expands in volume for small reductions in pressure. Under these conditions, blading becomesstrictly a reaction type design with the base of the blade solely impulse. The reason is due to the effect of therotation speed for each blade. As the volume increases, the blade height increases, and the base of the bladespins at a slower speed relative to the tip. This change in speed forces a designer to change from impulse at thebase, to a high reaction style tip.

Classical turbine design methods were developed in the mid 19th century. Vector analysis related the fluidflow with turbine shape and rotation. Graphical calculation methods were used at first. Formulae for the basicdimensions of turbine parts are well documented and a highly efficient machine can be reliably designed forany fluid flow condition. Some of the calculations are empirical or 'rule of thumb' formulae, and others arebased on classical mechanics. As with most engineering calculations, simplifying assumptions were made.

Velocity triangles can be used to calculate the basic performance of a turbine stage. Gas exits the stationaryturbine nozzle guide vanes at absolute velocity Va1. The rotor rotates at velocity U. Relative to the rotor, thevelocity of the gas as it impinges on the rotor entrance is Vr1. The gas is turned by the rotor and exits, relativeto the rotor, at velocity Vr2. However, in absolute terms the rotor exit velocity is Va2. The velocity trianglesare constructed using these various velocity vectors. Velocity triangles can be constructed at any sectionthrough the blading (for example: hub, tip, midsection and so on) but are usually shown at the mean stageradius. Mean performance for the stage can be calculated from the velocity triangles, at this radius, using theEuler equation:

\Delta\;h = u\cdot \Delta\;v_w

Hence:

\left (\frac{\Delta\;h}{T}\right) = \left(\frac{u}{\sqrt{T}}\right)\cdot\left(\frac{\Delta\;v_w}{\sqrt{T}}\right)


2 of 9 10/21/2013 11:14 PM

where:

\Delta\;h =\, specific enthalpy drop across stageT =\, turbine entry total (or stagnation) temperatureu =\, turbine rotor peripheral velocity\Delta\;v_w =\, change in whirl velocity

The turbine pressure ratio is a function of \left(\frac{\Delta\;H}{T}\right) and the turbine efficiency.

Modern turbine design carries the calculations further. Computational fluid dynamics dispenses with many ofthe simplifying assumptions used to derive classical formulas and computer software facilitates optimization.These tools have led to steady improvements in turbine design over the last forty years.

The primary numerical classification of a turbine is its specific speed. This number describes the speed of theturbine at its maximum efficiency with respect to the power and flow rate. The specific speed is derived to beindependent of turbine size. Given the fluid flow conditions and the desired shaft output speed, the specificspeed can be calculated and an appropriate turbine design selected.

The specific speed, along with some fundamental formulas can be used to reliably scale an existing design ofknown performance to a new size with corresponding performance.

Off-design performance is normally displayed as a turbine map or characteristic.

Steam turbines are used for the generation of electricity in thermal power plants, such as plants usingcoal, fuel oil or nuclear power. They were once used to directly drive mechanical devices such as ships'

propellers (for example the Turbinia, the first turbine-powered steam launch,[2]) but most suchapplications now use reduction gears or an intermediate electrical step, where the turbine is used togenerate electricity, which then powers an electric motor connected to the mechanical load. Turboelectric ship machinery was particularly popular in the period immediately before and during World WarII, primarily due to a lack of sufficient gear-cutting facilities in US and UK shipyards.Gas turbines are sometimes referred to as turbine engines. Such engines usually feature an inlet, fan,compressor, combustor and nozzle (possibly other assemblies) in addition to one or more turbines.Transonic turbine. The gas flow in most turbines employed in gas turbine engines remains subsonicthroughout the expansion process. In a transonic turbine the gas flow becomes supersonic as it exits thenozzle guide vanes, although the downstream velocities normally become subsonic. Transonic turbinesoperate at a higher pressure ratio than normal but are usually less efficient and uncommon.Contra-rotating turbines. With axial turbines, some efficiency advantage can be obtained if adownstream turbine rotates in the opposite direction to an upstream unit. However, the complicationcan be counter-productive. A contra-rotating steam turbine, usually known as the Ljungström turbine,was originally invented by Swedish Engineer Fredrik Ljungström (1875–1964) in Stockholm, and inpartnership with his brother Birger Ljungström he obtained a patent in 1894. The design is essentially amulti-stage radial turbine (or pair of 'nested' turbine rotors) offering great efficiency, four times as largeheat drop per stage as in the reaction (Parsons) turbine, extremely compact design and the type metparticular success in backpressure power plants. However, contrary to other designs, large steamvolumes are handled with difficulty and only a combination with axial flow turbines (DUREX) admitsthe turbine to be built for power greater than ca 50 MW. In marine applications only about 50 turbo-electric units were ordered (of which a considerable amount were finally sold to land plants) during

1917-19, and during 1920-22 a few turbo-mechanic not very successful units were sold.[3] Only a fewturbo-electric marine plants were still in use in the late 1960s (ss Ragne, ss Regin) while most land

plants remain in use 2010.Statorless turbine. Multi-stage turbines have a set of static (meaning stationary) inlet guide vanes thatdirect the gasflow onto the rotating rotor blades. In a statorless turbine the gasflow exiting an upstreamrotor impinges onto a downstream rotor without an intermediate set of stator vanes (that rearrange thepressure/velocity energy levels of the flow) being encountered.Ceramic turbine. Conventional high-pressure turbine blades (and vanes) are made from nickel basedalloys and often utilise intricate internal air-cooling passages to prevent the metal from overheating. Inrecent years, experimental ceramic blades have been manufactured and tested in gas turbines, with aview to increasing rotor inlet temperatures and/or, possibly, eliminating aircooling. Ceramic blades aremore brittle than their metallic counterparts, and carry a greater risk of catastrophic blade failure. Thishas tended to limit their use in jet engines and gas turbines to the stator (stationary) blades.Shrouded turbine. Many turbine rotor blades have shrouding at the top, which interlocks with that ofadjacent blades, to increase damping and thereby reduce blade flutter. In large land-based electricitygeneration steam turbines, the shrouding is often complemented, especially in the long blades of alow-pressure turbine, with lacing wires. These wires pass through holes drilled in the blades at suitabledistances from the blade root and are usually brazed to the blades at the point where they pass through.Lacing wires reduce blade flutter in the central part of the blades. The introduction of lacing wiressubstantially reduces the instances of blade failure in large or low-pressure turbines.Shroudless turbine. Modern practice is, wherever possible, to eliminate the rotor shrouding, thusreducing the centrifugal load on the blade and the cooling requirements.Bladeless turbine uses the boundary layer effect and not a fluid impinging upon the blades as in aconventional turbine.Water turbines

Pelton turbine, a type of impulse water turbine.Francis turbine, a type of widely used water turbine.Kaplan turbine, a variation of the Francis Turbine.Turgo turbine, a modified form of the Pelton wheel.Cross-flow turbine, also known as Banki-Michell turbine, or Ossberger turbine.

Wind turbine. These normally operate as a single stage without nozzle and interstage guide vanes. Anexception is the Éolienne Bollée, which has a stator and a rotor.Velocity compound "Curtis". Curtis combined the de Laval and Parsons turbine by using a set of fixednozzles on the first stage or stator and then a rank of fixed and rotating blade rows, as in the Parsons orde Laval, typically up to ten compared with up to a hundred stages of a Parsons design. The overallefficiency of a Curtis design is less than that of either the Parsons or de Laval designs, but it can besatisfactorily operated through a much wider range of speeds, including successful operation at lowspeeds and at lower pressures, which made it ideal for use in ships' powerplant. In a Curtis arrangement,the entire heat drop in the steam takes place in the initial nozzle row and both the subsequent movingblade rows and stationary blade rows merely change the direction of the steam. Use of a small section ofa Curtis arrangement, typically one nozzle section and two or three rows of moving blades, is usuallytermed a Curtis 'Wheel' and in this form, the Curtis found widespread use at sea as a 'governing stage' onmany reaction and impulse turbines and turbine sets. This practice is still commonplace today in marinesteam plant.Pressure compound multistage impulse, or "Rateau". The Rateau employs simple impulse rotorsseparated by a nozzle diaphragm. The diaphragm is essentially a partition wall in the turbine with aseries of tunnels cut into it, funnel shaped with the broad end facing the previous stage and the narrowthe next they are also angled to direct the steam jets onto the impulse rotor.

Almost all electrical power on Earth is produced with a turbine of some type. Very high efficiency steamturbines harness about 40% of the thermal energy, with the rest exhausted as waste heat.

Most jet engines rely on turbines to supply mechanical work from their working fluid and fuel as do all nuclearships and power plants.

Turbines are often part of a larger machine. A gas turbine, for example, may refer to an internal combustionmachine that contains a turbine, ducts, compressor, combustor, heat-exchanger, fan and (in the case of onedesigned to produce electricity) an alternator. Combustion turbines and steam turbines may be connected tomachinery such as pumps and compressors, or may be used for propulsion of ships, usually through anintermediate gearbox to reduce rotary speed.

Reciprocating piston engines such as aircraft engines can use a turbine powered by their exhaust to drive anintake-air compressor, a configuration known as a turbocharger (turbine supercharger) or, colloquially, a"turbo".

Turbines can have very high power density (i.e. the ratio of power to weight, or power to volume). This isbecause of their ability to operate at very high speeds. The Space Shuttle's main engines used turbopumps(machines consisting of a pump driven by a turbine engine) to feed the propellants (liquid oxygen and liquidhydrogen) into the engine's combustion chamber. The liquid hydrogen turbopump is slightly larger than anautomobile engine (weighing approximately 700 lb) and produces nearly 70,000 hp (52.2 MW).

Turboexpanders are widely used as sources of refrigeration in industrial processes.

Military jet engines, as a branch of gas turbines, have recently been used as primary flight controller in

post-stall flight using jet deflections that are also called thrust vectoring.[4] The U.S. FAA has also conducted astudy about civilizing such thrust vectoring systems to recover jetliners from catastrophes.

(See: Annales de chimie et de physique, vol. 21, page 183 (1822).) However, it was not until1824 that a committee of the Académie (composed of Prony, Dupin, and Girard) reported favorably onBurdin's memoir. See: Prony and Girard (1824) "Rappport sur le mémoire de M.

The Wind Energy Industry is Nothing New

Though our scientists may claim that they are inventing something new byusing wind as a source of generating energy, the truth is that wind is being usedfor centuries for this purpose. An example of this is an article published in1838, which clearly shows that even in those times, wind was considered animportant source of energy. Here are a few quotes that were recorded in thepast, which prove that wind was always important in generating energy. ViewComments

A Rose Wind Turbine by Any Other Name…

The one knock on wind energy is that it is not portable. Until recently, therewere few if any portable devices that were available to literally take windpower on the go. That is changing quick as there are several “back-pack” styledevices that are on the market. The Rose Wind Turbine is the latest inventionto be introduced to this ever growing energy niche. The Rose Wind Turbine is asmall portable device that is small enough to fit into the trunk of the car andbarely be noticed. However, once this portable wind turbine comes out, it issure to turn heads. View Comments

Jet Engines the Inspiration for New Wind Power Technology

Wind power has recently received a nice boost as one of the hottest forms ofenergy on the market. When comparing the recent market growth against allforms of energy, both renawables and non-renewables, wind turbines seem tobe jumping to the head of the pack. While it still has a way to go before itcatches up to solar, it is gaining ground rather quickly. Something that will helppick up the pace even further is new technology that is coming fromFloDesign. Their truly unique wind turbine is actually based on the design of ajet engine instead of the traditional windmills that we see all across the country.Their concept seems to be a simple one, but it extremely effective.

Is It Possible To Convert To 100% Wind Power?

With all the talk of going green, the question had been thrown out many timesif there will ever be a time that we can use nothing but renewable energy topower our world. A small island in Denmark is trying answer that question witha resounding yes as they power up every single day via nothing but windpower. The Danish island is the ideal setting as the wind literally never stopsblowing. The North Sea offers the perfect opportunity to capitalize on thewinds that come off of the sea and for them to use wind power as their primarysource of power. As a matter of fact, the wind power that they are using is theirONLY source of power. View Comments

Wind Turbine Power Goes Portable with Foldable Wind Generator

Renewable energy is one of the hottest things on the market right now but untilrecently, solar power has been getting most of the attention. While there areplenty of techno gadgets, like solar briefcases and solar laptop chargers, thatcan have solar power on the run, very few if any items exist for other sourcesof renewable energy to become portable. The foldable wind generator has allthe right ideas, but may still be just a bit ahead of its time. View Comments

The Kite Wind Generator

It's an expert estimation that the total energy stored in wind is 100 times higherthan actually needed by humans on this earth. The catch is that we have tolearn and devise ways to trap this wind power blowing across the planet earth.Experts tell us one more thing that most of the wind energy is available at highaltitude and we can’t manufacture turbines of that height. So we have to thinkof new ways to trap that wind power blowing at a significant height. Someexperts estimate that the total energy contained in wind is 100 times theamount needed by everyone on the planet. However, most of this energy is athigh altitudes, far beyond the reach of any wind turbine. View Comments

What factors affect the output of wind turbines?

Wind energy is undoubtedly one of the cleanest forms of producing power from a renewablesource. There is no pollution, there is no burning of fossil fuels, and unless something verydrastic happens, you don’t run out of wind. But it’s not like you can erect a wind turbineanywhere and it will start generating power for you. There are lots of factors that can make animpact on the amount of energy you can generate out of wind. View Comments

Small, Low Speed Wind Turbine

Most of us want to reduce our carbon footprints but currently most of the alternative energyproducts are simply unavailable for urban population that lives in metros. But gradually thescenario of alternative energy is changing and manufacturers have started thinking fromcommon person’s point of view. Recently EarthTronics, which is based in Muskegon,Michigan, has developed a wind turbine that can be used by individual homes. EarthTronicsalso claims that it can operate at speeds as low as 2 miles an hour. Consequently, homeownersthis fall will be able to buy a wind turbine at hardware stores that tackles the small wind industry's bete noire:slow wind. This turbine is named as Honeywell Wind Turbine and it will be distributed through Ace Hardwarestores in the U.S. It will be sold for $4,500. WindTronics developed the turbine and licensed the technology tobuildings systems giant Honeywell. View Comments

Using Existing Infrastructure for Wind Turbines

The Metropolis Magazine has been holding Next Generation Design Competition since 2003.They want to provide a platform for young designers to promote the spirit of activism, socialinvolvement, and entrepreneurship. They offer prize money of $ 10,000. But the real attractionis the publicity given to the projects of winners and runners-up. This recognition helps abstractideas take concrete forms. For 2009, the theme for the Next Generation Design Competitionwas: How do we fix our energy addiction? They offered some guidelines, "Think about how we live and work,what we use, how we get where we need to go, hidden costs to our pocket books and the environment, acrossthe whole design spectrum. Focus on one area that needs fixing—products, interiors, buildings and landscape,communication systems, or anything else you can imagine—and develop your idea fully. And above all, thinkof our energy addiction as a design problem at all scales." View Comments

WindCube Generates Electricity in Moderate Wind

Wind power is the fastest growing industry in the alternative energy sector. Wind turbinesgenerate clean and green power for us but they have certain precondition. One of it is thepower unit has to be set up in strong wind area. But Green Energy Technologies has developeda brand new wind power generator known as the WindCube. It is smaller compared to thenormal wind generator. WindCube is specially designed to set up on the roof of a building in

urban and rural areas. WindCube carries a 22 x 22 x 12 feet framework and its single unit can produce amaximum of 60kW of power. Mark L. Cironi, who is the president and founder of Green EnergyTechnologies, explains, "Building owners anywhere can consider being a part of the renewable energy picture.With WindCube, it’s not necessary to have the wind of Kansas or Nebraska to become a generator of windpower. In states with excellent renewable energy incentives, moderate wind and high electric rates, thepayback can be as little as three years." View Comments

Wind Energizer Donut for More Efficient Turbines

We all know about the impending future of the fossil fuels. Ultimately we will be forced tolook for alternative energy fuels. Those countries who have resources and infrastructure aretaking up these challenges very intelligently. Scientists and researchers know that existingalternative sources of energy can’t take up the challenges created by total exhaustion of fossilfuel. So they are continuously trying to better the existing technologies of the sources ofalternative fuels. This time Leviathan Energy presents a technology for new and existing wind farms toproduce more energy from a relatively small investment, a solution every manufacturer worth his/her saltwants i.e. more by investing less!
