Making Water Turbines Most Energy Efficient
How does a wind turbine’s output vary with wind pressure (height of water), the flow rate, size of the motor, and type of blade?
Introduction
There are many types of energy used today: Fossil fuels, coal, nuclear energy, solar energy, geothermal energy, hydrogen energy, hydroelectric energy, wind energy, and biofuels and biomass. Non-renewable energy sources such as fossil fuels and coal are diminishing since it cannot be recycled, unlike wind energy (renewable). Also, use of non-renewable energy like coal causes environmental issues. It can be dangerous to retrieve and also heavily pollutes the environment from use of it. The more we use non-renewable energy, the less there is, meaning the prices go up. Oil spills from off shore drilling such as the BP oil spill the Gulf of Mexico polluted sea water. Although nuclear energy is a renewable energy, it could cause a disaster to human beings if the nuclear energy plant is damaged, such as the Japan nuclear power plant disaster. It is desirable to use and develop renewable, clean and safe energy sources such as solar, wind, geothermal, hydroelectric, and hydrogen energy to decrease and prevent any risk of casualties or complications. Washington State produces the energy in the nation, and producing for itself 70 percent of electricity that is consumed. On a slightly bigger scale, 75 percent of America relies on water energy to power our homes and other facilities. Globally, hydroelectric power provides one fifth of the world’s energy.

How Dams Produce Electricity
Hydro energy has been used for a long time as a useful energy source to power water turbines, which is one method that is commonly used now to directly convert water energy into electric energy. You’ll see them put to use in dams, especially the well known Hoover dam or in the largest dam in the United…...

...Current Event 09-07-12 Wind Turbines I First Willacy County Turbine Farm Opens, More to Follow: A little over a year ago, a Chicago-based renewable energy company E.ON held a ribbon-cutting ceremony at the new site and began construction in October of 2011. The Magic Valley Wind Farm is what they decided to call it and it is located roughly 5 miles east of Raymondville. It is Willacy County's first wind farm. Within the last year, they put up 112 Danish-produced Vestas 1.8 megawatt turbines that generate more than 200 megawatts together, which is enough to power 60,000 houses. There was over 200 people hired for the construction phase of this wind farm and a staff of around 20 people on site. The project was approximately a 200 million dollar investment for E.ON and is the company’s 16th operational wind farm in North America upping the company’s generating power to 2,000 megawatts in Texas. The location of this wind farm is supposed to have minimal impact on wildlife and the environment due to environmental studies. During construction of this wind farm, more than 24 miles of public roads where constructed. Why do you think that is? I’m assuming they were constructed to cart in the enormous shafts and blades. There were more than 60,000 cubic yards of concrete poured and more than 50 miles of underground cable laid. Now if you head South of the Magic Valley project you will run into two more wind farms owned by Duke Energy that are supposed to operational at the end of......

...85 Hydraulic turbines—basic principles and state-of-theart computational fluid dynamics applications P Drtina* and M Sallaberger Sulzer Hydro AG, Zurich, Switzerland ¨ Abstract: The present paper discusses the basic principles of hydraulic turbines, with special emphasis on the use of computational fluid dynamics (CFD) as a tool which is being increasingly applied to gain insight into the complex three-dimensional (3D) phenomena occurring in these types of fluid machinery. The basic fluid mechanics is briefly treated for the three main types of hydraulic turbine: Pelton, Francis and axial turbines. From the vast number of applications where CFD has proven to be an important help to the design engineer, two examples have been chosen for a detailed discussion. The first example gives a comparison of experimental data and 3D Euler and 3D Navier–Stokes results for the flow in a Francis runner. The second example highlights the state-of-the-art of predicting the performance of an entire Francis turbine by means of numerical simulation.

...energy for the near and distant future. There are many advantages to wind energy; it is a sustainable energy source that is non-polluting. With a 30 percent annual increase, wind is the world’s fastest-growing bulk power electricity source. Montana has a bright future in wind energy. The American Wind Energy Association ranked Montana’s wind-energy potential in the top five in the nation. Currently, the state has several utility-scale wind farms in operation. History of Wind Energy Wind energy has been used by civilizations throughout time. As early as 5000 B.C., wind energy propelled boats up and down rivers. Simple windmills pumped water in China in 200 B.C. Wind energy technology and its applications continued to grow and diversify throughout the ages. By the late 19th century, settlers of the New World were using windmills to pump water, and eventually, to generate electricity. Small windmills were used until the late 1920s to bring electricity to rural Americans. Farm and ranch communities in Montana used wind generators that produced direct current (DC) electricity that was often stored in batteries. However, these systems were short-lived due to the Rural Electrification Act (REA) of 1936. The REA subsidized the construction of rural electric distribution lines, transmission lines, and electrical generation facilities through low interest loans. This government act dramatically increased the number of rural Montana communities that received grid-connected......

Wind Turbines vs Animals

...air, water, or general landscape. When several wind turbines are grouped together they are called wind farms. These wind farms offer many benefits to the environment, economy, and people whom are receiving the wind generated electricity. But without proper research and improper planning schemes wind farms are being placed in migratory paths for birds and bats killing or injuring them, attract and kill pollinator insects, and (according to some) decrease the aesthetic beauty of the landscape. The first wind farm in the United States was in Crocheted Mountains, New Hampshire in 1980. Since then they have grown to 119 wind farms in the United States. There are two basic forms of wind turbines, vertical axis and horizontal axis wind turbines. The vertical axis turbine blades have several designs but the commonality between the designs is that they have open spaces some people refer to as lattice spaced openings. Horizontal axis turbine blades look like propellers on an airplane. It is estimated that roughly 573,000 birds are injured or killed annually, roughly 600,000 bats are injured or killed annually and innumerable pollinator insects are killed annually by wind farms. The problem with vertical axis turbines is that the spaces in the blades are wonderful perching and nest building sites for birds when they aren’t moving. So when the blades start to move the birds are injured and the nest and eggs are destroyed. The problem with horizontal axis turbines is......

Thermal Steam-Turbine Power Plants

...Thermal Steam-turbine Power Plants Large steam-turbine plants have two forms: condensing plants, electric power plants. The great masses of hot steam, having accomplished the mechanics work in the turbines of condensing steam-turbine plants, are condensed - i.e. are cooled down and turned back into distilled water, and returned to the boiler for production of steam to activate the turbine. Condensation of steam takes place in condensers where the hot steam is cooled when it comes in contact with tubes through which cooling water, supplied from a water reservoir (river or lake), is circulated. This cooling water, after it takes the heat from the spent steam, is returned to the water source carrying along with it the unutilized heat energy. This water is called the circulating water. The importance of the distilled water for feeding steam boilers is extremely great since chemical clean water decreases the formation of scale in the boiler tubes, and thus, makes their service life longer. Condensing plants of large generating capacity are built close in sources of fuel, in order not to transport large quantities of fuel over considerable distances. The electric power generated in such plants is transmitted over long distances for the supply of large industrial regions. So these plants are called regional thermal power plants. Heat and electric power plants, in addition to electric power generation, also supply heat to closely......

...Wind Turbine San Jose State University, Charles W. Davidson College of Engineering E10 Introduction to Engineering By Justin DeCastro, Cari Geldreich, Hugo Quiroz, and Ashley Mishra March 24, 2011 Professor Athanasiou Section 6 Project Summary The project that was assigned in lab was the wind turbine lab. The objective of this lab was to develop and construct a wind turbine that would create enough energy to conduct electricity. The goal of the assignment was to construct the most creative and stable structure so that it would withstand high winds. After constructing the turbine, which was 17 inches high and weight 255 grams, the next task was to test its stiffness using various amounts of weights and to look for the displacement. The maximum amount of displacement by the turbine was 4.81 mm. After finding out how stiff the turbine was, the next task was to measure the amount of power the turbine generated. The turbine worked quite well except for the fact that the blade broke within the first few minutes. The blade speed started out with 9703 RPM and went down to as low as 6000RPM when it had 6 light bulbs on. The turbine successfully completed all the objectives with ease. The only thing that it could’ve done better in was the stiffness test because it displaced more weight than it needed to.

...The Water Wheel The water wheel has helped to shape modern society because it was one of the earliest machines. It dates back to dates Before Christ. Once it was being used its popularity grew fast and spread quickly. At first there was no real engineering but a wheel with paddles in the center. It was first used to for grinding grains. As people used it for more things like driving sawmills and pumps, they also looked for ways to make the water wheel more efficient. They created the overshot wheel, the undershot wheel, and the breast wheel. The designs were for different uses and generated different amount of horsepower depending on the user’s needs. They also started making water wheels out of cast iron. People were always looking for ways to make it more efficient and some inventions were very successful like the cast-iron gearing which brought all wood construction to an end. Since they were always looking for more efficient ways this also brought to people inventing turbines and even windmills. Even now a days small companies use water wheels instead of turbines because they are more affordable and the payback is greater. They are also very affordable to maintain. If it wasn’t for this early machine that started it all maybe we wouldn’t have evolved so fast in this technology. Maybe they would have been grinding grains by hand for a couple hundred years more. Hydro-electric dams are descendants from water wheels, as they also take advantage of the movement of water......

...important thing that every individual should think is optimal use of non-renewable resources. For a country like India the growth of population is very high which proportionately increases the usage of energy. So it is necessary to educate the people on the harsh environmental impact of modern living. If we come up with small, creative and affordable changes which decreases the usage of non-renewable energy we can make our planet Green. Many countries started implementing alternate ways like solar power, wind power etc which is good initiative to other countries. Other important phenomenon we have to think are waste management and water management. These things forced me to apply your company. I’m enthusiastic about listening to music and playing volley ball. In my Engineering I did a project on exergy analysis on gas turbine power plant (exergy of a system is the maximum useful work possible during the process that brings the system in to equilibrium). This project deals with How to increase the efficiency of the system with the same input of power. I participated in the green technology work shop which was conducted in my college. I had 1year work experience in prawn feed manufacturing unit during this job I have seen so many changes in the system. When I joined in this company there were no waste collecting bins, no proper greenery, no standing fans to the workers working near the boiler, but after the pollution audit by senior government......

I will also introduce them to the basics of wind turbines and what a wind turbine site consists of. The best audience for this presentation is anyone without previous knowledge of wind turbines. This presentation is designed to generally educated people on wind turbines and wind sites. It is not designed to go into real depth with wind turbines. If there was anyone interested in getting wind turbines on their land this presentation would help to let them know what to expect. They type of audience that would resist this knowledge is any group that works in fossil fuels. These communities usually worry that their jobs our in jeopardy because of green energy. This topic is important because of the increase in wind turbines throughout the United States and world. It is important for us to understand the basics of what they do and what a plant is made up. The reason this is important is because we the people vote to allow turbines in our communities. The more information we have on the technology the better decision people can make for their communities. Research shows that due to better technology and the demand for green energy Wind Turbine development is increasing across the United States.

...kind. There are many different types of renewable sources that we can use. Wind, water, sun and geothermal heat are a few that are readily available for use. However, we have to think of the pros and cons and the human interaction that comes with all four of these. Some of the pros and cons are the same with these, although from here-in there will only be talk of wind power and the good and bad sides to using it. Wind power is a totally renewable resource. Since, there is wind all over the world turbines could go up anywhere, on land and in the sea. The pros to putting wind turbines are that they are green. They do not produce any radiation or other type of pollution that can affect the local area. Efficiency always comes in to play when planning something that big and they are very efficient, both with space and what they provide. Some of the largest turbines offer power to generate enough watts for 600 homes; they also can protect against power outages, whereas telephone poles cannot since they can get knocked down more easy, for example in an ice storm. Wind power has been around since the early 1800’s when it was used to power water pumps to get water out of wells to go to farming. And, besides, once the structure is up and running and paid for the power is, for the most part, free. With the pros stated, now it is time for the cons to be gone over. Since the biggest part of a wind turbine is the wind, it can be hard to say where and for how long a certain place it......

...Wind Turbines: As the demand for energy is constantly increasing, due to an ever increasing congested population, mankind finds itself in a predicament, where do we continue to source the needed power to run our world. The old 20th century industrial age response is no longer applicable to modern day society, whereby; coal, gas and other non renewable limited resources are depleting. The 21st century has been presented with this detrimental world altering issue. Thankfully we now live in what is known as the technological era. This new century brought about with it new ideas and new developments- accordingly it is these developments in thinking and resources that will pave the way for alternate sources of power. New responses to this ever-present issue include hyrdo-electricity, a legitimate and controllable sources of power, solar power; another renewable resource whose presence is ever increasing in today’s developing world. Arguably the most efficient form of renewable and environmentally friendly energy is wind power. The ability to harness the power generated by the winds. The concept of harnessing the power of wind is no new invention, not even relatively new, in fact the idea has been around since 5000B.C whereby it was first utilized by the early Egyptians to propel their boats down the Nile river. Over the centuries, advancements to the concept continued and by 200B.C simple windmills in china were being developed to pump water for irrigation whilst the middle...

Turbine Engines

...Turbine Engines The history of turbine engines date back to nearly a century ago when Frank Whittle was the first to register a patent in 1930; six years later Hans von Ohain registered his independent work (Bellis, 2012). Frank Whittle, as an English aviation engineer and pilot, gained private financial support to start designing and manufacturing his first turbojet in January 1930 (Bellis, 2012). His first engine was a single-stage centrifugal compressor attached to a single-stage turbine was tested in 1937 (Bellis, 2012). The jet engine has become very complex engine based on simple concepts; in simplest terms, the jet engine produces thrust for flight by compressing, combustion, and accelerating air out the exhaust faster than when it came in the inlet. Throughout my career, I have maintained, troubleshot, and repaired several different types of turbine engines, all of which are similar because of this theory of operation. When looking at a jet engine, everyone usually sees the fan blades, but before this component, there is the inlet, or intake, which is the structure in front of the fan. For aircraft that cannot fly supersonically, the inlet is a basic housing that directs air straight into the fan; for much faster aircraft, the inlet is longer and contains a slight curve as it leads to the fan. This is because when the aircraft is flying at supersonic speeds, the air entering the jet engine must be slowed to subsonic speeds (“the jet engine,” n.d.). It is...

Design of a Kaplan Turbine

...1. Blade Design: The design of the blade does not just depend on the stress analysis; several other factors play significant roles as well. The leading edge is thicker than the trailing edge for a streamlined Flow. Furthermore, the blade should be as thin as possible to improve cavitation Characteristics; it is thicker near the flange becoming thinner and thinner towards the tip. In Addition, the blade has to be distorted on the basis of the tangential velocity. Blade design is the most complex thing in Kaplan turbine. It consists of six steps. 1. Velocity triangle is evaluated at the leading and Trailing edge of the blade. 2. Angle of distortion of the chord lengths (β∞). 3. Lift Coefficients. 4. Chord length to Spacing (L/t) ratio. 5. Drag Coefficient. 6. Profile. 2.1. Velocity Triangle: U U As shown in the figure different types of velocities occur as the fluid flows from the blades of this turbine. Thorough understanding of the velocity triangle (fig 1. 1) is necessary for a good design. Figure 1.1 Figure 1.1 β∞ β∞ Wu Wu Cu Cu Wm Wm Cm Cm Blade Tangential Velocity ……….
