THAWT is a variant of The coastal areas like Maldives have also been successfully Darrieus Turbine. Horizontal Axis Water Turbine is a turbine started using more of the energy using such turbines. The HAWT has been proved a boon for such a country which which harnesses electrical energy at the expense of water overwhelmingly depends upon fossil fuels for their kinetic energy. As the name suggests it has a horizontal axis of electrification. This technology has efficiently helped them to rotation. Due to this they can be installed directly inside the curb with various social and economic crisis [2]. The water body, beneath the flow. These turbines do not require complicated remote households and communities of Brazil any head and are also known as zero head or very low head have been electrified with these small hydro-kinetic projects, water turbines. This Project aims at the fabrication of such a where one unit can provide up to 2kW of electric power [11]. -

(USA) Online ISSN: 2249-4596 Print ISSN:0975-5861 Design, Performance and Maintenance of Francis Turbines By Hermod Brekke Abstract - The aim for turbine design is to increase the efficiency and avoid cavitation and fractures during operation. A brief discussion on a the design philosophy during the last 60 years with will be presented. The structural design has moved from castings and riveted plates to fully fabricated structures of high tensile strength steel in the stationary parts and stainless 13/4 Cr/Ni or 16/5 (17/4) Cr/Ni steel have substituted the 13/1 Cr/Ni in runners. The paper also includes an ancient runner design with plate steel blades moulded in cast steel at crown and band. Such high head runners, put in operation in 1950, hve been in operation in good condition Norway until about 15 years ago. A discussion on stress analyses and fatigue problems of pressure loaded parts and high frequency fatigue in runners, will be presented GJRE-A Classification : FOR Code: 290501 Design, Performance and Maintenance ofFrancis Turbines Strictly as per the compliance and regulations of : © 2013.

Comparative Performance Evaluation of Pelton Wheel and Cross Flow Turbines for Power Generation
EUROPEAN MECHANICAL SCIENCE Research Paper e-ISSN: 2587-1110 Comparative Performance Evaluation of Pelton Wheel and Cross Flow Turbines for Power Generation Oyebode O. O.1* and Olaoye J. O.2 1Department of Food, Agricultural and Biological Engineering, Kwara State University, Malete, Kwara State, Nigeria. 2Department of Agricultural and Biosystems Engineering, University of Ilorin, Ilorin, Kwara State, Nigeria. ORCID: Oyebode (0000-0003-1094-1149) Abstract The performance of two micro hydro power turbines (Pelton Wheel and Cross Flow Turbines) were evaluated at the University of Ilorin (UNILORIN) dam. The Dam has a net head of 4 m, flow rate of 0.017m3 and theoretical hydropower energy of 668W. The two turbines were tested and the optimized value of operating conditions namely; angle of inclination (15o above tangent, tangential and 15o below tangent), height to impact point (200mm, 250mm and 300mm) and length to impact point (50mm, 100mm and 150mm) were pre-set at their various levels for both Turbines. The optimum values of the process output or measured parameters were determined statistically using a 33X2 factorial experiment in three replicates. An optimum Turbine speed (538.38rpm) in off load condition was achieved at 250mm height to impact point, 150mm length to impact point and angle at tangential inclination. Similar combination also yielded an optimum turbine torque of 46.16kNm for Pelton Wheel Turbine. For the Crossflow Turbine, an optimum turbine speed of 330.09rpm was achieved by pre-setting 250mm height to impact point, 100mm length to impact point and 15º below tangent. Same combination also yielded an optimum turbine torque of 39.07kNm. -
Harvesting Energy from In-Pipe Hydro Systems at Urban and Building Scale
International Journal of Smart Grid and Clean Energy Harvesting energy from in-pipe hydro systems at urban and building scale Marco Casini * Department of Planning, Design, and Technology of Architecture (PDTA), Sapienza University of Rome, Via Flaminia 72, 00196 – Rome, Italy Abstract In addition to photovoltaic and wind systems, nowadays in-pipe water to wire power systems are becoming particularly interesting for the integration of renewable resources at urban and building scale because of the potential to harness clean energy from excess head pressure in urban and domestic water pipelines. Able to operate across a wide range of head and flow conditions, these particular micro hydro power systems can be deployed in municipalities, energy-intensive industries and agricultural irrigation districts providing a consistent amount of clean and continuous energy without the typical intermittency of wind and solar and at the same time helping in pipelines management and maintenance. The article presents an overview of the different types of in-pipe hydro systems available on the market and illustrates their possible applications at the urban and building scale and the benefits achievable in terms of energy production compared to other renewable such as photovoltaic and wind systems. Keywords: In-pipe hydro systems, energy harvesting, renewable energy, small hydro, building integrated renewable energy, renewable energy at urban scale, distributed energy 1. Introduction Hydropower is a mature and cost-competitive renewable energy source that plays a strategic essential role in XXI century electricity mix, contributing to more than 16% of electricity generation worldwide (more than 3500 TWh) and about 85% of global renewable electricity [1], [2]. -

If the City agrees to all liabilities should an accident occur, then the area can be open to the public.) By Kate Ramunni, 12/23/2008, ConnPost.com SHELTON -- The owner of the Shelton Canal Co. is again appealing to the Federal Energy Regulatory Commission to relocate the portion of his property that is open to the public. As part of the company's license, and as a condition of the zoning approval it received more than two decades ago, a portion of the property at the end of Canal Street must be open to the public for recreation. It has over the years been used for fishing. McCallum Industries co-owner Joseph Szarmach has filed a request for another hearing on the issue, a month after FERC reversed its initial approval of the relocation. That action came after the state Department of Environmental Protection appealed the initial approval. "We are going through this process to amend our license because it is standard procedure; however, we continue to believe it is our right to close the canal area due to safety concerns," Szarmach said, most notably its proximity to the dam. "The DEP, at the city's urging, is advocating full and unfettered access to a pool of water into which we dump 34,000 gallons of water per second," Szarmach said. -

The DEIS fails to adequately assess the potential impacts of constructing and operating new storage at Temperance Flat, and even its flawed analysis demonstrates that the alternatives will result in significant adverse environmental impacts. Yet the document fails to consider feasible mitigation measures to address the significant environmental impacts that are likely to result from the alternatives analyzed in the DEIS. Overall, as documented in detail in the pages that follow, the DEIS fails to comply with the requirements of CEQA and NEPA. In particular, the DEIS: Fails to consider a reasonable range of alternatives; Fails to incorporate climate change into the operational modeling -

This study attempted to analyze the potential energy of hydropower if it were implemented at the Triplett Creek Dam, the Cave Run Lake Dam, and at a total of various sites across the state of Kentucky. Methodology The researcher utilized different methods of analysis to address each of the four research questions. The first step in the assessment of the potential of a hydroelectric system was to determine the amount of obtainable power at all of the potential sites. -
