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.

Turbulence is one of the key issues in tackling engineering flow problems. As powerful computers and accurate numerical methods are now available for solving the flow equations, and since engineering applications nearly always involve turbulence effects, the reliability of CFD analysis depends increasingly on the performance of the turbulence models. This series of symposia provides a forum for presenting and discussing new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. The papers in this set of proceedings were presented at the 5th International Symposium on Engineering Turbulence Modelling and Measurements in September 2002. They look at a variety of areas, including: Turbulence modelling; Direct and large-eddy simulations; Applications of turbulence models; Experimental studies; Transition; Turbulence control; Aerodynamic flow; Aero-acoustics; Turbomachinery flows; Heat transfer; Combustion systems; Two-phase flows. These papers are preceded by a section containing 6 invited papers covering various aspects of turbulence modelling and simulation as well as their practical application, combustion modelling and particle-image velocimetry.

The new edition of a classic textbook on combustion principles and processes, covering the latest developments in fuels and applications in a student-friendly format Principles of Combustion provides clear and authoritative coverage of chemically reacting flow systems. Detailed and accessible chapters cover key combustion topics such as chemical kinetics, reaction mechanisms, laminar flames, droplet evaporation and burning, and turbulent reacting flows. Numerous figures, end-of-chapter problems, extensive reference materials, and examples of specific combustion applications are integrated throughout the text. Newly revised and expanded, Principles of Combustion makes it easier for students to absorb and master each concept covered by presenting content through smaller, bite-sized chapters. Two entirely new chapters on turbulent reacting flows and solid fuel combustion are accompanied by additional coverage of low carbon fuels such as hydrogen, natural gas, and renewable fuels. This new edition contains a wealth of new homework problems, new application examples, up-to-date references, and access to a new companion website with MATLAB files that students can use to run different combustion cases. Fully updated to meet the needs of today’s students and instructors, Principles of Combustion: Provides problem-solving techniques that draw from thermodynamics, fluid mechanics, and chemistry Addresses contemporary topics such as zero carbon combustion, turbulent combustion, and sustainable fuels Discusses the role of combustion emissions in climate change and the need for reducing reliance on carbon-based fossil fuels Covers a wide range of combustion application areas, including internal combustion engines, industrial heating, and materials processing Containing both introductory and advanced material on various combustion topics, Principles of Combustion, Third Edition, is an essential textbook for upper-level undergraduate and graduate courses on combustion, combustion theory, and combustion processes. It is also a valuable reference for combustion engineers and scientists wanting to better understand a particular combustion problem.

Extensively using experimental and numerical illustrations, CombustionPhenomena: Selected Mechanisms of Flame Formation, Propagation, and Extinction provides a comprehensive survey of the fundamental processes of flame formation, propagation, and extinction. Taking you through the stages of combustion, leading experts visually display, mathematically explain, and clearly theorize on important physical topics of combustion. After a historical introduction to the field, they discuss combustion chemistry, flammability limits, and spark ignition. They also study counterflow twin-flame configuration, flame in a vortex core, the propagation characteristics of edge flames, instabilities, and tulip flames. In addition, the book describes flame extinction in narrow channels, global quenching of premixed flames by turbulence, counterflow premixed flame extinction limits, the interaction of flames with fluids in rotating vessels, and turbulent flames. The final chapter explores diffusion flames as well as combustion in spark- and compression-ignition engines. It also examines the transition from deflagration to detonation, along with the detonation wave structure. With downloadable resources of images that beautifully illustrate a range of combustion phenomena, this book facilitates a practical understanding of the processes occurring in the conception, spread, and extinguishment of a flame. It will help you on your way to finding solutions to real issues encountered in transportation, power generation, industrial processes, chemical engineering, and fire and explosion hazards.
