Lukas Pehle beschäftigt sich mit der transienten thermischen und strukturmechanischen Analyse einer 19-stufigen Mitteldruck-Dampfturbine. Dafür errechnet und bewertet er Zeitdauern und auftretende Spannungen, um ein breites Spektrum an Vorwärm-Szenarien beschreiben zu können. Das dabei verwendete und weiterentwickelte Festkörpermodell wird an experimentellen Daten kalibriert, um im Anschluss eine Parameterstudie durchführen zu können. Mithilfe des untersuchten Konzepts des Vorwärmens von Dampfturbinen können thermisch induzierte Spannungen beim Kraftwerksstart verringert werden. Dieses Buch leistet aufgrund der dadurch flexibleren Kraftwerke einen wichtigen Beitrag zur Versorgungssicherheit nach der Energiewende, also für den Übergang von fossilen Energieträgern und der Kernenergie zu einer nachhaltigen Energieversorgung mittels erneuerbarer Energien. Der Inhalt Grundlagen physikalischer Phänomene wie Strömungsmechanik, Wärmeübertragung und Festkörpermechanik Modellierungen zur transienten Temperatur- und Spannungsverteilung einer Dampfturbine Parameterstudie Die Zielgruppen Dozierende, Studierende und Praktizierende aus der Energietechnik, dem Maschinenbau und der Wärmeübertragung Der Autor Lukas Pehle arbeitet zurzeit beim Institut für Kraftwerkstechnik, Dampf- und Gasturbinen in Aachen. Er untersucht den Heißgaseinzug in Radseitenräumen von Gasturbinen mithilfe einer Versuchsturbine und forscht in der Dampfturbinen-Vorwärmung.

"We know, from repeated failures to predict and prevent catastrophes ranging from the Great Tohoku Earthquake to the global financial crisis of 2008, that complex adaptive systems, such as those found in nature or in economies, are actually very hard to predict, much less influence. Today, we face environmental degradation caused in large part by the use of fossil fuels, ever-declining efficiencies in extracting them, a pace of development for renewable energy insufficient for replacement of the fossil fuels we are burning through, and population growth that is likely to add two billion people globally by 2045. Despite partial recovery since the financial crisis of 2008, growth remains sluggish, and large budget deficits persist across much of the developed world. Meanwhile, developing states face their own challenges, stemming from unbalanced growth. Against this backdrop, and in light of the urgent need to pay closer heed to our environment, the last thing the world needs is an energy crisis triggered not merely by recurrent scares over supply, but by more lasting structural changes in our ability to use fossil fuels with reckless abandon. Buying Time applies lessons learned the hard way from the global economic crisis of the past decade, to offer an overview of the state of the environment and our energy future. Grounded in subtle thinking about complex systems, including the economy, energy, and the environment, this book underscores the connections linking them all. Kaz Makabe is a veteran financial systems expert who lived through the Fukushima Daiichi nuclear disaster. He nevertheless concludes that nuclear energy is the bridge than can help us cross over the abyss we face."

"Reliable, affordable, and technically recoverable energy is central to the nation's economic and social vitality. The United States is both a major consumer of geologically based energy resources from around the world and - increasingly of late - a developer of its own energy resources. Understanding the national and global availability of those resources as well as the environmental impacts of their development is essential for strategic decision making related to the nation's energy mix. The U.S. Geological Survey Energy Resources Program is charged with providing unbiased and publicly available national- and regional-scale assessments of the location, quantity, and quality of geologically based energy resources and with undertaking research related to their development. At the request of the Energy Resources Program (ERP), this publication considers the nation's geologically based energy resource challenges in the context of current national and international energy outlooks. Future Directions for the U.S. Geological Survey's Energy Resources Program examines how ERP activities and products address those challenges and align with the needs federal and nonfederal consumers of ERP products. This study contains recommendations to develop ERP products over the next 10-15 years that will most effectively inform both USGS energy research priorities and the energy needs and priorities of the U.S. government"--Publisher's description.
