Book Description
An understanding of the intricacies in the turbulent combustion process may be a key to solving many of the current energy and environmental problems. The essential nature of turbulent combustion can be derived from the interaction between stochastic flow fluctuations and deterministic molecular processes, such as chemical reaction and transport processes. Undoubtedly, this is one of the most challenging fields of engineering science today, requiring as it does the interaction of scientists and engineers in the respective fields of chemical kinetics and fluid mechanics. The 28 papers in this volume review recent advances in these two disciplines providing new insights into the fundamental processes, addressing a great deal of recent progress. This progress ranges from descriptions of elementary chemical kinetics, to working those descriptions into combustion calculations with large numbers of elementary steps, to improved understanding of turbulent reacting flows and advances in simulations of turbulent combustion. The contributions will inspire further research on many fronts, advancing the understanding of combustion processes, as well as fostering a growing interdisciplinary cooperation.

Book Description
A work on turbulent premixed combustion is important because of increased concern about the environmental impact of combustion and the search for new combustion concepts and technologies. An improved understanding of lean fuel turbulent premixed flames must play a central role in the fundamental science of these new concepts. Lean premixed flames have the potential to offer ultra-low emission levels, but they are notoriously susceptible to combustion oscillations. Thus, sophisticated control measures are inevitably required. The editors' intent is to set out the modeling aspects in the field of turbulent premixed combustion. Good progress has been made on this topic, and this cohesive volume contains contributions from international experts on various subtopics of the lean premixed flame problem.

Book Description
Today the study of materials is concerned with the underlying thermodynamic and chemical processes involved in the manufacture and processing of a wide range of materials - metals, ceramics, semi-conductors, plastics and composites. For the first time, this book provides a quantitative description and examples of the application of physical chemical concepts to the processing and degradation of metallic and other inorganic materials, from the atomic scale to the analysis of industrial processes. Thermochemical Processes: Principles and Models deals with processes dominated in turn by the gas phase (such as chemical vapour deposition), the solid phase (such as powder metallurgy electroceramics and high-temperature corrosion) and the liquid phase (such as extraction metallurgy and glass-making). C. B. Alcock provides information which will prove invaluable to academics and workers involved in high temperature industries and in particular to those with an interest in the scientific analysis of processes - which will be most useful to those working in the field of modelling. - First ever quantitative approach to the subject of Thermochemical processing - Companion volume to Kubachewski et al

Book Description
Volume II of the High Speed Aerodynamics and Jet Propulsion series. This volume includes treatments of all aspects of combustion necessary to the development of jet and rocket engines. Originally published in 1956. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
The combustion of fossil fuels remains a key technology for the foreseeable future. It is therefore important that we understand the mechanisms of combustion and, in particular, the role of turbulence within this process. Combustion always takes place within a turbulent flow field for two reasons: turbulence increases the mixing process and enhances combustion, but at the same time combustion releases heat which generates flow instability through buoyancy, thus enhancing the transition to turbulence. The four chapters of this book present a thorough introduction to the field of turbulent combustion. After an overview of modeling approaches, the three remaining chapters consider the three distinct cases of premixed, non-premixed, and partially premixed combustion, respectively. This book will be of value to researchers and students of engineering and applied mathematics by demonstrating the current theories of turbulent combustion within a unified presentation of the field.

Book Description
The safe operation of plants is of paramount importance in the chemical, petrochemical and pharmaceutical industries. Best practice in process and plant safety allows both the prevention of hazards and the mitigation of consequences. Safety Technology is continuously advancing to new levels and Computational Fluid Dynamics (CFD) is already successfully established as a tool to ensure the safe operation of industrial plants. With CFD tools, a great amount of knowledge can be gained as both the necessary safety measures and the economic operation of plants can be simultaneously determined. Young academics, safety experts and safety managers in all parts of the industry will henceforth be forced to responsibly judge these new results from a safety perspective. This is the main challenge for the future of safety technology. This book serves as a guide to elaborating and determining the principles, assumptions, strengths, limitations and application areas of utilizing CFD in process and plant safety, and safety management. The book offers recommendations relating to guidelines, procedures, frameworks and technology for creating a higher level of safety for chemical and petrochemical plants. It includes modeling aids and concrete examples of industrial safety measures for hazard prevention.

Book Description
Whether in the Stone Age or in Greek mythology, fire has always been the essence of life. As G.G. Brown put it in 1928, “Combustion is without exaggeration the most important reaction to the human race. All human and animal existence depends upon combustion as its course of energy.” This book provides a detailed description of the elements of combustion, offering descriptive figures, illustrative quips, and analogies to facilitate understanding. It begins with some historical highlights of the understanding of combustion and technological progresses. It then discusses the thermodynamic and chemical kinetics underlying the fast chemical reactions, before expounding on the fundamental combustion wave, or flame. After this, the book moves onto the premixed turbulent flame and the spark-ignited turbulent flame, before considering the diffusion-controlled, non-premixed flame in both laminar and turbulent forms. The book concludes with explanations of wonderful natural combustion, fire, fire-retarding slime and DNA, and the amazing bombardier beetle.
