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.
