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.

Over the past three decades, information in the aerospace and mechanical engineering fields in general and turbomachinery in particular has grown at an exponential rate. Fluid Dynamics and Heat Transfer of Turbomachinery is the first book, in one complete volume, to bring together the modern approaches and advances in the field, providing the most up-to-date, unified treatment available on basic principles, physical aspects of the aerothermal field, analysis, performance, theory, and computation of turbomachinery flow and heat transfer.

Presenting a unified approach to turbomachinery fluid dynamics and aerothermodynamics, the book concentrates on the fluid dynamic aspects of flows and thermodynamic considerations rather than on those related to materials, structure, or mechanical aspects. It covers the latest material and all types of turbomachinery used in modern-day aircraft, automotive, marine, spacecraft, power, and industrial applications; and there is an entire chapter devoted to modern approaches on computation of turbomachinery flow. An additional chapter on turbine cooling and heat transfer is unique for a turbomachinery book.

The author has undertaken a systematic approach, through more than three hundred illustrations, in developing the knowledge base. He uses analysis and data correlation in his discussion of most recent developments in this area, drawn from over nine hundred references and from research projects carried out by various organizations in the United States and abroad.

This book is extremely useful for anyone involved in the analysis, design, and testing of turbomachinery. For students, it can be used as a two-semester course of senior undergraduate or graduate study: the first semester dealing with the basic principles and analysis of turbomachinery, the second exploring three-dimensional viscid flows, computation, and heat transfer. Many sections are quite general and applicable to other areas in fluid dynamics and heat transfer. The book can also be used as a self-study guide to those who want to acquire this knowledge.

The ordered, meticulous, and unified approach of Fluid Dynamics and Heat Transfer of Turbomachinery should make the specialization of turbomachinery in aerospace and mechanical engineering much more accessible to students and professionals alike, in universities, industry, and government.

Turbomachinery theory, performance, and analysis made accessible with a new, unified approach

For the first time in nearly three decades, here is a completely up-to-date and unified approach to turbomachinery fluid dynamics and aerothermodynamics. Combining the latest advances, methods, and approaches in the field, Fluid Dynamics and Heat Transfer of Turbomachinery features:

• The most comprehensive and complete coverage of the fluid dynamics and aerothermodynamics of turbomachinery to date
• A spotlight on the fluid dynamic aspects of flows and the thermodynamic considerations for turbomachinery (rather than the structural or material aspects)
• A detailed, step-by-step presentation of the analytical and computational models involved, which allows the reader to easily construct a flowchart from which to operate
• Critical reviews of all the existing analytical and numerical models, highlighting the advantages and drawbacks of each
• Comprehensive coverage of turbine cooling and heat transfer, a unique feature for a book on turbomachinery
• An appendix of basic computation techniques, numerous tables, and listings of common terminology, abbreviations, and nomenclature

Broad in scope, yet concise, and drawing on the author's teaching experience and research projects for government and industry, Fluid Dynamics and Heat Transfer of Turbomachinery explains and simplifies an increasingly complex field. It is an invaluable resource for undergraduate and graduate students in aerospace and mechanical engineering specializing in turbomachinery, for research and design engineers, and for all professionals who are—or wish to be—at the cutting edge of this technology.

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."

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.

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.

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.

The aim of this work, consisting of 9 individual, self-contained booklets, is to describe commercial vehicle technology in a way that is clear, concise and illustrative. Compact and easy to understand, it provides an overview of the technology that goes into modern commercial vehicles. Starting from the customer's fundamental requirements, the characteristics and systems that define the design of the vehicles are presented knowledgeably in a series of articles, each of which can be read and studied on their own. In this volume, Fuel Consumption and Consumption Optimization, the main focus is placed on the factors for optimizing consumption in the conventional vehicle. Fuel consumption can be optimized by four different factors: the technology of the vehicle, the conditions of its operation, the behavior of the driver and the maintenance and upkeep of the vehicle. These aspects are described in a way that is easily understood for training and practical application.
