Download or read book Investigating Main and High Speed Shaft Bearing Reliability through Uptower Testing written by and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most prevalent failure modes in wind turbine drivetrains are main bearing failures stemming from micropitting, white etching or axial cracks in gearbox bearings, and generator bearing failures. These failures are neither well understood nor accounted for in design standards; consequently, the mitigation strategies being developed and fielded may only partially address the physics of failure and can take years to assess. The U.S. Department of Energy continues to support research programs to investigate the influence of rolling element sliding on the formation of bearing axial cracks and main bearing micropitting.
Download or read book Long term Research Challenges in Wind Energy A Research Agenda by the European Academy of Wind Energy written by Gijs van Kuik and published by Springer. This book was released on 2016-09-21 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the view of European wind energy experts on the long-term research challenges to be solved in order to develop wind energy beyond the applications of today and tomorrow. By this book, the European Academy of Wind Energy (eawe), representing universities and institutes with a significant wind energy programme in 14 countries, wants to: identify current technological and scientific barriers and to stimulate new creative ideas to overcome these barriers define priorities for future scientific research rethink our scientific view of wind energy stimulate the cooperation among researchers in fundamental and applied sciences towards wind energy research The eawe has discussed these long-term research with an explicit focus on a longer-term perspective, in contrast to research agendas addressing short- to medium-term research activities. In other words, this long-term research agenda is driven by problems and curiosity, addressing basic research and fundamental knowledge in 11 research areas, ranging from physics and design to environmental and societal aspects. Because of the very nature of this initiative, this document does not intend to be permanent or complete. It shows the vision of the experts of the European Academy of Wind Energy, but other views may be possible. The eawe sincerely hopes that it will spur an even more intensive discussion worldwide within the wind energy community.
Download or read book Wind Turbines written by Erich Hau and published by Springer Science & Business Media. This book was released on 2005-12-12 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind Turbines addresses all those professionally involved in research, development, manufacture and operation of wind turbines. It provides a cross-disciplinary overview of modern wind turbine technology and an orientation in the associated technical, economic and environmental fields. It is based on the author's experience gained over decades designing wind energy converters with a major industrial manufacturer and, more recently, in technical consulting and in the planning of large wind park installations, with special attention to economics. The second edition accounts for the emerging concerns over increasing numbers of installed wind turbines. In particular, an important new chapter has been added which deals with offshore wind utilisation. All advanced chapters have been extensively revised and in some cases considerably extended

Download or read book Wind Vision written by U. S. Department U.S. Department of Energy and published by CreateSpace. This book was released on 2015-03-18 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed roadmap of technical, economic, and institutional actions by the wind industry, the wind research community, and others to optimize wind's potential contribution to a cleaner, more reliable, low-carbon, domestic energy generation portfolio, utilizing U.S. manu-facturing and a U.S. workforce. The roadmap is intended to be the beginning of an evolving, collaborative, and necessarily dynamic process. It thus suggests an approach of continual updates at least every two years, informed by its analysis activities. Roadmap actions are identified in nine topical areas, introduced below.

Download or read book Heads in Beds written by Jacob Tomsky and published by Anchor. This book was released on 2012-11-20 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of Kitchen Confidential and Waiter Rant, a rollicking, eye-opening, fantastically indiscreet memoir of a life spent (and misspent) in the hotel industry. “Highly amusing."—New York Times Jacob Tomsky never intended to go into the hotel business. As a new college graduate, armed only with a philosophy degree and a singular lack of career direction, he became a valet parker for a large luxury hotel in New Orleans. Yet, rising fast through the ranks, he ended up working in “hospitality” for more than a decade, doing everything from supervising the housekeeping department to manning the front desk at an upscale Manhattan hotel. He’s checked you in, checked you out, separated your white panties from the white bed sheets, parked your car, tasted your room-service meals, cleaned your toilet, denied you a late checkout, given you a wake-up call, eaten M&Ms out of your minibar, laughed at your jokes, and taken your money. In Heads in Beds he pulls back the curtain to expose the crazy and compelling reality of a multi-billion-dollar industry we think we know. Heads in Beds is a funny, authentic, and irreverent chronicle of the highs and lows of hotel life, told by a keenly observant insider who’s seen it all. Prepare to be amused, shocked, and amazed as he spills the unwritten code of the bellhops, the antics that go on in the valet parking garage, the housekeeping department’s dirty little secrets—not to mention the shameless activities of the guests, who are rarely on their best behavior. Prepare to be moved, too, by his candor about what it’s like to toil in a highly demanding service industry at the luxury level, where people expect to get what they pay for (and often a whole lot more). Employees are poorly paid and frequently abused by coworkers and guests alike, and maintaining a semblance of sanity is a daily challenge. Along his journey Tomsky also reveals the secrets of the industry, offering easy ways to get what you need from your hotel without any hassle. This book (and a timely proffered twenty-dollar bill) will help you score late checkouts and upgrades, get free stuff galore, and make that pay-per-view charge magically disappear. Thanks to him you’ll know how to get the very best service from any business that makes its money from putting heads in beds. Or, at the very least, you will keep the bellmen from taking your luggage into the camera-free back office and bashing it against the wall repeatedly.
