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

plant with the equipment purchased in order to liquefy the gas and also construction time is reduced (Berger,E, Forg, W...2003 pg 12). Not only can it be economically effective but it is also environmentally friendly. Description /Procedure The below diagram is of how the mixed fluid cascade process operates. The referigerents are made up of methane, ethane, propane and nitrogen (Shukre,F and Wheeler,F 2004 pg 3). Firstly, the natural gas (fed stream) comes in from the top and goes through three

primary product line. Mr Harnett, Tucker’s president, comprehensively explained what the basis of such restructuring through a memo. It was stated that the three new divisions are namely the commercial jet engines, military jet engines and utility turbines. Every division is to be managed by a newly appointed vice president who will directly report to the company's president, Mr. Harnett. All of these divisions will have their own engineering, manufacturing, accounting departments etc. Also, it will

3 Mass Flow rate analysis 4 Exhaust Gas 6 Results 7 Conclusion 8 Reference 9 Equivalent ratio of a gas turbine Introduction and Procedure For this experiment, a two shaft gas turbine (ET792) was used. At the core of ET792 are a so-called gas generator and a free-running power turbine. The gas generator consists of a radial compressor, a combustion chamber and a radial turbine. The compressor and turbine are mounted on a shaft. The gas turbine works as an open cyclic process, with the

the environment. Many are interested in the source of renewable energy so that natural resources are not diminished. There are many alternatives in the market to choose from. Wind turbines are one of alternatives (Linzmeier, 2009). Now the question that comes to mind is, is wind energy green? Wind turbines produce cleaner energy & bring no hazardous effects to the atmosphere by giving any pollutant emissions; however, it does come with casualties. As the U.S. energy industry inches

kinds of turbo charger? Axial-flow Turbocharger * Axial-flow turbochargers are defined by the manner in which the fuel flows through the turbine. With axial-flow turbochargers the fuel flow comes through the wheel in an axial direction. With this type of turbocharger expansion of the gas from the exhaust creates an output the helps the turbine to rotate the compressor. As the size of the vehicle is important in determining the vehicle's correct turbocharger, it is important to consider that

fertilizers, plastics, paints, pesticides, medicines, and synthetic fibers (Berg & Hager, 2009). Most environmental problems associated with oil are caused by burning and transporting it. Burning oil produces carbon dioxide, which is a greenhouse gas, so it contributes to global warming. It can also lead to acid deposition because the combustion of oil is the leading cause of nitrogen oxides. Nitrogen oxides inhibit plant growth and they are involved in photochemical smog and acid deposition (Berg

Hodges 1 Daulton Hodges English 1010: Composition 1 22 March 2012 Supercharger vs Turbocharger One of the most commonly used ways to give a vehicle more horsepower and torque is by forced induction. There are two different ways to force induct a vehicle. One is a Supercharger, and the other is a Turbocharger. The conflict with this between people is deciding which one is better. Both superchargers and turbochargers have their advantages and disadvantages, some of which are similar. Choosing

energy produced by wind power, it is unpredictable because it can spread out. Wind power does not generate if wind is not strong enough. Moreover, not everywhere that turbine for generator can be installed. The reading continues by bringing up the point of the cost of wind energy. Wind energy is affordable compare to coal, oil, and gas because the wind is free. Alternatively, the speaker once again resists this idea by the initial investment for produce wind energy is expensive. A generator for produce
