Modern rotating machinery, particularly turbomachinery, is frequently being designed to operate at higher speeds than in the past. Consequently, there is an increased need to balance high-speed rotors. The purpose of this book is to provide the engineering student or practicing engineer with a single, complete reference on high-speed rotor balancing. To this end, a detailed analytical background and practical application procedures are presented for each of the principal high-speed rotor balancing methods, i.e. modal balancing, influence coefficient balancing and the Unified Balancing Approach. This information is supplemented and supported through a presentation of the theoretical development of synchronous rotor vibration and a brief overview of rigid rotor balancing techniques and machines. This is the first time this material is available in a single, concise volume, together with detailed descriptions of application procedures.

Originating in the process compressor industry, this text primarily addresses: rotating equipment engineers, project engineers, engineering contractors, and compressor user companies in oil and gas field operations, natural gas processing, petroleum refining, petrochemical processing, industrial refrigeration, and chemical industries. It enables the reader to assess compressors and defines the constraints influencing the compressor design.

This 1992 book provides a coherent and comprehensive treatment of the thermodynamics and gas dynamics of the practical Stirling cycle. Invented in 1816, the Stirling engine is the subject of worldwide research and development on account of unique qualities - silence, indifference to heat source, low level of emissions when burning conventional fuels and an ability to function in reverse as heat pump or refrigerator. The student of engineering will discover an instructure and illuminating case study revealing the interactions of basic disciplines. The researcher will find the groundwork prepared for various types of computer simulation, Those involved in the use and teaching of solution methods for unsteady gas dynamics problems will find a comprehensive treatment on nonlinear and linear wave approaches, for the Stirling machine provides an elegant example of the application of each. The book will be of use to all those involved in researching, designing or manufacturing Stirling prime movers, coolers and related regenerative thermal machines.

Thermal systems are essential features in power, chemical processing, air conditioning, and other industries where heat and power are used. As the cost and complexity of designing thermal systems have increased, the need to understand and improve the design process has also grown. This book describes recent progress in the design of thermal systems. The book begins with a brief history and outline of developments in thermal system design. Chapters then discuss computer design tools for the power and chemical industries, predicting physical properties with computational tools, the use of 'pinch analysis' to improve thermal efficiency, applications of the exergy concept, the emerging concept of thermoeconomics, and the potential for artificial intelligence and expert systems in the design of thermal systems. With chapters written by internationally recognised authorities, the book offers a state-of-the-art review for both researchers and practitioners in mechanical, aerospace, chemical, and power engineering.

This book discusses electric power transmission and related policy issues. Transmission is a prominent federal issue because of a perceived need to improve reliability and reduce costs, transmission's role in meeting national energy goals (such as increased use of renewable electricity), and the potential efficiency advantages of "smart grid" modernisation. Proposals before the 111th Congress for changing federal transmission law and regulations to meet these and other objectives include the Clean Renewable Energy and Economic Development Act and the majority staff transmission siting draft of the Senate Energy and Natural Resources Committee. Transmission development and regulation are complex and sometimes contentious policy areas and this book reviews transmission planning and permitting, financing and cost allocation, system modernisation and the smart grid and transmission system reliability.

During this century, as no other, the two themes of mathematics and heat transfer have become inextricably intertwined, and it was with this underlying sentiment that this volume was conceived. It includes contributions from fifteen countries throughout the world, covering various problems in heat transfer. The contributors work in diverse fields and include mathematicians, theoretical engineers, experimentalists and industrialists.

Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students exploring pumps and pump design. This book is about the fluid dynamics of liquid turbomachines, particularly pumps. It focuses on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows, and turbomachinery as well as basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps discussed in the three final chapters. The book is richly illustrated and includes many practical examples."

On its original publication in 1973, this book was the first reference for engineers to fully present the science of boiling and condensation. It dealt especially with the problems of estimating heat transfer rates and pressure drops, with particular attention to the occurrence of boiling and condensation in the presence of forced flows within pipes. The new third edition was written primarily for design and development engineers in the chemical process, power generation, and refrigeration industries, and is meant to be an aid in the design of heat exchangers. It covers recent advances and significantly broadens coverage to flows over tube bundles, with extensive new treatment of two-phase heat transfer regarding refrigerants and petrochemicals. Many new problems have been added at the end of each chapter to enhance the book's use as a text in advanced courses on two-phase flow and heat transfer. Instructors using the book as a course text may obtain full solutions to the end-of-chapter problems by writing to: Science Marketing Dept., Oxford University Press, 198 Madison Avenue, New York, NY 10016 (please include school name and course identification), or by faxing (212) 726-6442.

Engineering curricula are notoriously demanding. One way to make the material easier to grasp and more fun to learn is to emphasize the experimental or "hands-on" aspects of engineering problems. This unique book is about learning through active participation in laboratory experiments, and it specifically aims to dispel some of the mystery so many students associate with the study of thermodynamics and heat transfer. In it, the author presents a collection of experiments in heat transfer and thermodynamics contributed by leading engineering educators. The experiments have been tested, evaluated, and proved successful for classroom use. Each experiment follows the same step-by-step format, which includes the objective of the experiment, apparatus needed, procedure, suggested headings, and references. The experiments use apparatus that is easily built or attainable. Among the topics covered are heat conduction, convection, boiling, mixing, diffusion, radiation, heat pipes and exchangers, and thermodynamics. The book will be especially useful as a companion to standard heat transfer and thermodynamics texts.

This is the first comprehensive history of the steam engine in fifty years. It follows the development of reciprocating steam engines, from their earliest forms to the beginning of the twentieth century when they were replaced by steam turbines.

Heat engines that use gases as the working fluid in a closed system model were discussed in this book. Otto cycle, Diesel, Miller, and Dual cycle are internal combustion engines. Stirling cycle is an external combustion engine. The Otto cycle is a spark-ignition reciprocating engine made of an isentropic compression process, a constant volume combustion process, an isentropic expansion process, and a constant volume cooling process. The thermal efficiency of the Otto cycle depends on its compression ratio. The compression ratio is defined as r=Vmax/Vmin. The Otto cycle efficiency is limited by the compression ratio because of the engine knock problem. The Diesel cycle is a compression-ignition reciprocating engine made of an isentropic compression process, a constant pressure combustion process, an isentropic expansion process, and a constant volume cooling process. The thermal efficiency of the Otto cycle depends on its compression ratio and cut-off ratio. The compression ratio is defined as r=Vmax/Vmin. The cut-off ratio is defined as rcutoff=Vcombustion off/Vmin. The Dual cycle involves two heat addition processes, one at constant volume and one at constant pressure. It behaves more like an actual cycle than either Otto or Diesel cycle. The Lenoir cycle was the first commercially successful internal combustion engine. The Stirling cycle and Wicks cycle are attempt to achieve the Carnot efficiency. The Miller cycle uses variable valve timing for compression ratio control to improve the performance of internal combustion engines.

Solar energy is derived ultimately from the sun. It can be divided into direct and indirect categories. Most energy sources on Earth are forms of indirect solar energy, although we usually don't think of them in that way. Coal, oil and natural gas derive from ancient biological material which took its energy from the sun (via plant photosynthesis) millions of years ago. All the energy in wood and foodstuffs also comes from the sun. Movement of the wind (which causes waves at sea), and the evaporation of water to form rainfall which accumulates in rivers and lakes, are also powered by the sun. Therefore, hydroelectric power and wind and wave power are forms of indirect solar energy. Direct solar energy is what we usually mean when we speak of solar power -- it is the use of sunlight for heating or generating electricity. Solar energy research and applications have been receiving increasing attention throughout the world as solar energy must play a much greater role in the energy mix in upcoming years. This book examines new research in this frontier field.

In The Last Ten Years, author Brian J. Dickson presents stunning colour photographs from the collections of three enthusiasts of the Seafield Railway Club in north London. Meeting regularly at New Southgate station to record the steam-handled traffic, their focus was initially on all things connected with the former London and North Eastern Railway, but as steam traction became restricted to smaller and smaller areas of operation, regular visits were made further afield, to the north-east of England, Scotland and the former London Midland and Scottish Railway sheds and lines. This record of steam locomotion in its final years of mainline usage, from 1959 to 1968, is sure to enhance any steam railway enthusiast's library.

Andreas Schneider untersucht einen elektrifizierten Antriebsstrang, bestehend aus einem Verbrennungsmotor mit teilhomogener Verbrennung, einer elektrischen Maschine und einem elektrisch beheizten Katalysator. Die eigens entwickelte Antriebsstrangsimulation wird uber eine neuartige Betriebsstrategie, welche aus den parallel agierenden Modulen ECMS und Phlegmatisierung besteht, geregelt. Die Auswertung am Motorenprufstand zeigt, dass durch die Elektrifizierung des Antriebsstrangs eine Reduktion aller Schadstoffemissionen in Phasen geringer Geschwindigkeitsanforderungen erzielt werden kann. Gleichzeitig wird eine Verschiebung der Stickstoffoxidemissionen in Phasen hoher Geschwindigkeitsanforderungen erreicht, was sich als vorteilhaft fur einen SCR-Einsatz erweisen wurde. Zusatzlich kann eine Reduktion des Kraftstoffverbrauchs mit dem vorgestellten Fahrzeugkonzept realisiert werden.

Beim Maschinenausrichten an gekuppelten Maschinensatzen gibt es einen breiten Anwenderkreis, der mit Messmitteln oder Messgeraten diese geometrisch nur scheinbar einfache Aufgabe loest. Nicht ausreichend ist haufig der fachliche Hintergrund der Techniker, Meister und Ingenieure, vor allem zu den vielfaltigen Auswirkungen und zur Diagnose von Fehlausrichtungen im Betrieb. Um eine Ausrichtmessung zuverlassig ausfuhren, begleiten oder vermitteln zu koennen, wird der Hauptzielgruppe ein UEberblick uber die praktischen Methoden vermittelt. In der VDI 2627 wurden diese Inhalte an Getrieben ansatzweise beschrieben; der Autor trug zur Verbesserung einer Neuerscheinung dieser Richtlinie bei. Hier setzt auch die Buchreihe "Einfuhrung in die Maschinendiagnose" an. Vom physikalischen Hintergrund bis zur praktischen Anwendung werden Grundlagen und Erfahrungen leicht verstandlich dargestellt und mit praktischen Beispielen illustriert. Die vertiefte, umfassende Diagnose von Bauteilschaden von der "Initial- bis zur Wurzelursache" uber die Behandlung praktischer Fehlerquellen an Maschinen bis zu deren Abhilfe und echten Vorbeugung werden in dieser Buchreihe behandelt.

The Rolls-Royce Merlin is the most recognisable aero engine in the world. It powered the Battle of Britain aircraft, the Spitfire and Hurricane, as they defended the shores of Britain against the Luftwaffe, foiling Hitler's plans to invade in summer 1940. It also powered the Lancasters and Halifaxes of Bomber Command as they went on their missions of destruction to the German heartland. And the 'wooden wonder', the Mosquito, was powered by the Merlin, its pinpoint bombing accuracy and reconnaissance work proving vital to the war effort. For the Americans, the Merlin was the power plant of the Mustang escort fighter that protected the US Air Force B-17 Flying Fortress and B-29 Super Fortress bombers on their daylight raids to the enemy. The P-51 was also used in the North African, Mediterranean and Pacific theatres. So the Merlin worked day and night to secure the eventual Allied victory. It has rightfully been described as the most significant aircraft piston engine in history and in the twenty-first century its distinctive 'drone' can still be heard over England as the Battle of Britain Memorial Flight take to the air on special occasions - most recently on the centenary of the RAF - with its Lancaster leading the Merlin-powered Spitfires and Hurricanes in formation. Retired military and commercial pilot Gordon Wilson tells the human story of the development of the engine and its operational use during the war, featuring the voices of air crew who relied on this technological tour de force.
