"An Introduction to Combustion" remains unique in its niche as an introductory-level textbook that is suitable for undergraduate and graduate students and for practicing engineers. Material is presented in an easy-to-understand way and a wide range of subjects is covered in combustion and fuels. In the fourth edition material has been added related to the role of combustion in a sustainable energy future and modern open-source software has been integrated throughout.

This introduction reviews why combustion and radiation are important, as well as the technical challenges posed by radiation. Emphasis is on interactions among turbulence, chemistry and radiation (turbulence-chemistry-radiation interactions - TCRI) in Reynolds-averaged and large-eddy simulations. Subsequent chapters cover: chemically reacting turbulent flows; radiation properties, Reynolds transport equation (RTE) solution methods, and TCRI; radiation effects in laminar flames; TCRI in turbulent flames; and high-pressure combustion systems. This Brief presents integrated approach that includes radiation at the outset, rather than as an afterthought. It stands as the most recent developments in physical modeling, numerical algorithms, and applications collected in one monograph.
