The book "Introduction to Physics and Chemistry of Combustion" offers a comprehensive introduction to the fundamental chemical and physical processes associated with combustion and related phenomena in gaseous combustible mixtures. It addresses the mechanisms of reaction wave propagation and the dynamics of gases that occur during the combustion process. The combustion of gas mixtures, including flames, explosions, and detonations, is presented as a complex interplay of chemical reactions and physical movements. The focus is on premixed gas combustion, which is of great practical importance in modern applications such as engines and gas turbines. The book is aimed at students from various disciplines, including physics, chemistry, mechanical engineering, computer science, mathematics, and astrophysics, and provides foundational knowledge about combustion mechanisms and their applications.
