Book Description
In general, combustion is a spatially three-dimensional, highly complex physi co-chemical process oftransient nature. Models are therefore needed that sim to such a degree that it becomes amenable plify a given combustion problem to theoretical or numerical analysis but that are not so restrictive as to distort the underlying physics or chemistry. In particular, in view of worldwide efforts to conserve energy and to control pollutant formation, models of combustion chemistry are needed that are sufficiently accurate to allow confident predic tions of flame structures. Reduced kinetic mechanisms, which are the topic of the present book, represent such combustion-chemistry models. Historically combustion chemistry was first described as a global one-step reaction in which fuel and oxidizer react to form a single product. Even when detailed mechanisms ofelementary reactions became available, empirical one step kinetic approximations were needed in order to make problems amenable to theoretical analysis. This situation began to change inthe early 1970s when computing facilities became more powerful and more widely available, thereby facilitating numerical analysis of relatively simple combustion problems, typi cally steady one-dimensional flames, with moderately detailed mechanisms of elementary reactions. However, even on the fastest and most powerful com puters available today, numerical simulations of, say, laminar, steady, three dimensional reacting flows with reasonably detailed and hence realistic ki netic mechanisms of elementary reactions are not possible.

Book Description
This fully revised and updated edition of "Handbook of Combustion" - the standard work on this topic - comes with 30% more content and an extended new editorial team with two more renowned experts. The new edition combines the strength of the previous one while increasing the scope by additional chapters on unconventional natural gas, boiling liquid expanding vapor explosion (BLEVE) and smog formation, and by expanding existing topics, e.g., biofuels and chemical looping combustion. The work is divided in five topics: 1) Fundamentals and Safety, 2) Combustion Diagnostics and Pollutants, 3) Gaseous and Liquid Fuels, 4) Solid Fuels, and 5) New Technologies. Cross-references in and between the topics guide the reader to the content of interest and provide access to additional subjects. This major reference summarizes all significant information on combustion such as the chemistry, physics, and modeling of combustion processes, spectroscopic methods, safety regulations, pollutants formation, fuel types and, not the least, environmental impacts. The Handbook of Combustion is a complete and impressive work written for academic as well as industrial researchers and developers. Reviewer quotes (amazon): "... the entire area of combustion, including gasification and new technologies, is described in a clear and comprehensive way." "... this is a unique handbook, which closes a big gap in the literature."

Book Description
Phenomenology of Diesel Combustion and Modeling Diesel is the most efficient combustion engine today and it plays an important role in transport of goods and passengers on land and on high seas. The emissions must be controlled as stipulated by the society without sacrificing the legendary fuel economy of the diesel engines. These important drivers caused innovations in diesel engineering like re-entrant combustion chambers in the piston, lower swirl support and high pressure injection, in turn reducing the ignition delay and hence the nitric oxides. The limits on emissions are being continually reduced. The- fore, the required accuracy of the models to predict the emissions and efficiency of the engines is high. The phenomenological combustion models based on physical and chemical description of the processes in the engine are practical to describe diesel engine combustion and to carry out parametric studies. This is because the injection process, which can be relatively well predicted, has the dominant effect on mixture formation and subsequent course of combustion. The need for improving these models by incorporating new developments in engine designs is explained in Chapter 2. With “model based control programs” used in the Electronic Control Units of the engines, phenomenological models are assuming more importance now because the detailed CFD based models are too slow to be handled by the Electronic Control Units. Experimental work is necessary to develop the basic understanding of the pr- esses.

Book Description
Introduces the field of hydrogen technology and explains the basic chemistry underlying promising and innovative new technologies This new and completely updated edition of Introduction to Hydrogen Technology explains, at an introductory level, the scientific and technical aspects of hydrogen technology. It incorporates information on the latest developments and the current research in the field, including: new techniques for isolating and storing hydrogen, usage as a fuel for automobiles, residential power systems, mobile power systems, and space applications. Introduction to Hydrogen Technology, Second Edition features classroom-tested exercises and sample problems. It details new economical methods for isolating the pure hydrogen molecule. These less expensive methods help make hydrogen fuel a very viable alternative to petroleum-based energy. The book also adds a new chapter on hydrogen production and batteries. It also provides in-depth coverage of the many technical hurdles in hydrogen storage. The developments in fuel cells since the last edition has been updated. Offers new chapters on hydrogen production, storage, and batteries Features new sections on advanced hydrogen systems, new membranes, greenhouse gas sensors and updated technologies involving solar and wind energies Includes problems at the end of the Chapters, as well as solutions for adopters This book is an introduction to hydrogen technology for students who have taken at least one course in general chemistry and calculus; it will also be a resource book for scientists and researchers working in hydrogen-based technologies, as well as anyone interested in sustainable energy.

Book Description
Nonsteady Flame Propagation provides information pertinent to flame propagation in gaseous media. This book focuses on linearized treatments and the comparison of their results with experimental observations. Organized into nine chapters, this book begins with an overview of the challenge of nonlinear problems and examines the essentially nonlinear character of the flame phenomena, which has been artificially suppressed in analyses by the use of linearized perturbation treatments. This text then summarizes the development regarding rocket-shaped burners. Other chapters consider the advantages as well as the limitations of linearized analyses. This book discusses as well a general treatment of the discontinuous-flame-front model and summarizes the results of studies of burner that use secondary air. The final chapter deals with re-examining the possibilities of using pulsating combustion in propulsion or in other applications. This book is a valuable resource for chemical engineers, chemists, scientists, and research workers.
