Design and Analysis of a Kaplan Turbine Runner Wheel
Proceedings of the 3rd World Congress on Mechanical, Chemical, and Material Engineering (MCM'17) Rome, Italy – June 8 – 10, 2017 Paper No. HTFF 151 ISSN: 2369-8136 DOI: 10.11159/htff17.151 Design and Analysis of a Kaplan Turbine Runner Wheel Chamil Abeykoon1, Tobi Hantsch2 1Faculty of Science and Engineering, University of Manchester Oxford Road, M13 9PL, Manchester, UK [email protected] 2Devison of Applied Science, Computing and Engineering, Glyndwr University Mold Road, LL11 2AW, Wrexham, UK Abstract - The demand for renewable energy sources such as hydro, solar and wind has been rapidly growing over the last few decades due to the increasing environmental issues and the predicted scarcity of fossil fuels. Among the renewable energy sources, hydropower generation is one of the primary sources which date back to 1770s. Hydropower turbines are in two types as impulse and reaction where Kaplan turbine is a reaction type which was invented in 1913. The efficiency of a turbine is highly influenced by its runner wheel and this work aims to study the design of a Kaplan turbine runner wheel. First, a theoretical design was performed for determining the main characteristics where it showed an efficiency of 94%. Usually, theoretical equations are generalized and simplified and also they assumed constants of experienced data and hence a theoretical design will only be an approximate. This was confirmed as the same theoretical design showed only 59.98% of efficiency with a computational fluids dynamics (CFD) evaluation. Then, the theoretically proposed design was further analysed where pressure distribution and inlet/outlet tangential velocities of the blades were analysed and corrected with CFD to improve the efficiency of power generation. -

Hydraulic Turbines and Auxiliary Equipment
BR01B1848 ETDE-BR--0278 Hydraulic Turbines and Auxiliary Equipment Reporter: Mr. Luo Gaorong Deputy Director of International Centre of PCH of ONU in China .. Small Hydro Power in China L The Procedures of Small Hydro Power (SHP) Construction 1. The SHP Planning 1.1. The planning of middle and small rivers. Since all SHP stations are built on middle and small rivers, it is necessary to mnduct river planning before the SHP design, which shall be in accordance with multipurpose water resources utilization and cascade optimal development. To be more specific, river planning should take such purposes into account, namely, flood control, water supply, navigation, power generation, environmental protection, natural scene improvement, improvement of surviving conditions of human being, etc so as to develop water resources fully and rationally. At present, most rivers in China have been planned and the planning can be modified annually according to the social and economic development. The planning can be accomplished by water conse~ancy bureaus (departments) at the provincial, prefectural or county level as the river basin varies. 1.2. The planning of rural grid. Most SHP has been incorporated into the rural grid, so the electricity demand of the grid and load forecasting determine the SHP development. At present, most rural SHP grids face such a contradiction, i.e. abundant electricity during the flood season vs. electricity shortage during dry season, which can be relaxed a little bit by exchanging electricity with the national grid. So constructing SHP stations with yearly regulating reservoir has become a priority, 1.3. The SHP planning. -

Design and Flow Analysis of Enhanced Kaplan Turbine
DESIGN AND FLOW ANALYSIS OF ENHANCED KAPLAN TURBINE Shri Krishna Gupta1, Anshu Prakash Maurya2, 3 4 Ankit kumar Maurya Priyanka Jhavar 1P G Scholar,deparment of mechanical engineering SSSUTMS, Bhopal (India) 2Assistant Professor, Ashoka Institute of Technology and Management, Varanasi UP (India) 3P G Scholar,deparment of mechanical engineering SSSUTMS, Bhopal (India) 4HOD, SSSUTMS, Bhopal, ABSTRACT This paper presents the study of fluid flow analysis in enhanced Kaplan turbine. By changing the blade design, we consume the more energy even at low pressure of water flow in the Turbine. This turbine works on the principle of Archimedean screw that convert’s the potential energy of water on an upstream level into kinetic energy. Water flows into the turbine and its weight presses down onto the blades of the turbine, which in turn forces the turbine to turn. Water flows freely off the end of the turbine into the river. Also this study focused to found the variations of velocity components and the pressure by average circumferential area (ACA) from inlet to outlet of the blades and used as factors to analyzed the flow inside the blades, the results of this analysis shows a good prediction of the flow behavior inside the blades and this lead to acceptable blade design, which can be used in Kaplan turbine. Blade complex geometry and design have been developed by using the coordinates point system on the blade in PRO-E /CREO software. Based on the flow rate and heads, blade profiles are analyzed using ANSYS software to check and compare the output results for optimization of the blades for improved results which show that by changing blade profile angle and its geometry can be optimized using the computational techniques with changes in CAD models. -

Testimony of Gia D. Schneider Chairman and CEO Natel Energy
Testimony of Gia D. Schneider Chairman and CEO Natel Energy, Inc. Before the Committee on Science and Technology, Subcommittee on Energy and Environment United States House of Representatives “Marine and Hydrokinetic Energy Technology: Finding the Path to Commercialization” December 3, 2009 Introduction Good morning Chairman Gordon, Ranking Member Hall, and members of the Committee and Subcommittee. My name is Gia Schneider and I am a co-founder and the chairman and CEO of Natel Energy, Inc. I greatly appreciate the opportunity to share Natel Energy’s story with the Committee, and to discuss the roles of the federal government and private industry in developing technologies suitable for low head hydropower energy generation. Natel Energy Background Natel Energy, Inc. is a California and Texas-based company that is commercializing a new hydropower technology called the Linear Hydroengine or SLH, which could cut the cost of low-head turbines by as much as 50%. Our mission is to maximize the use of existing water infrastructure in the U.S. to bring on- line cost-effective, distributed, baseload, renewable energy from low head hydropower sources with minimal negative environmental impacts. Indeed, in certain cases, we believe the potential exists to implement projects that both deliver renewable energy and create positive environmental co-benefits. For example, we are evaluating the potential to incorporate renewable energy into low dams in the Midwest whose primary purpose is to create wetlands that trap nutrient pollutants which are a primary cause of the dead zone in the Gulf of Mexico. If we can successfully incorporate low head hydropower generation into some of these projects, we could create an additional revenue source for Midwest farmers, bring new renewable energy onto the grid, and reduce nutrient pollution. -
Learn About Turbines
Learn about Turbines Akashdeep Singh, AEO TURBINES • The word ‘turbine’ was coined by Claude Bourdin in the early 19th century and is derived from the Latin word for 'whirling' or a 'vortex'. • Water under pressure contains energy. • Turbines convert this energy into rotating mechanical energy. • Flowing water is directed onto the Blades of a turbine Runner, creating a force on the blades, thus transferring kinetic energy from the water flow to the turbine. Where are Turbines used • Hydroelectric schemes use the kinetic energy of moving water to produce electricity. This water is put through a turbine, which in turn drives a generator that generates electricity. Types of Hydro-Electric Schemes • Run of the river: Turbine and generator are located at the dam or along its side – e.g. Bhakhra Dam. • Diversion: The supply of water is taken from a dammed river or lake to a remote powerhouse containing the turbine and generator – e.g. Slapper (the dam is at Pandoh, the water flows through two tunnels & a channel to power house at Slapper) . • Pumped storage: This scheme incorporates two reservoirs. At times of low demand, electricity is used to pump the water from lower to upper basin. This extra water is then released to create power at a time when demand is high – e.g. Tehri Hydropower Complex where Tehri dam forms the upper reservoir and Koteshwar dam serves as lower reservoir. Types of Turbines • Water wheel Turbine • Impulse Turbine • Kaplan Turbine • Francis Turbine • Pelton Turbine • Cross flow Turbine WATER WHEEL TURBINE • Have you seen a water wheel in a field? These were very common till a few decades ago to water the fields. -
