Combustion Theory delves deeper into the science of combustion than most other texts and gives insight into combustions from a molecular and a continuum point of view. The book presents derivations of the basic equations of combustion theory and contains appendices on the background of subjects of thermodynamics, chemical kinetics, fluid dynamics, and transport processes. Diffusion flames, reactions in flows with negligible transport and the theory of pre-mixed flames are treated, as are detonation phenomena, the combustion of solid propellents, and ignition, extinction, and flamibility pehnomena.

CHAPTER 1

Summary of Relevant Aspects of Fluid Dynamics and Chemical Kinetics

Since combustion problems requiring theoretical analysis are primarily concerned with the flow of reacting and diffusing gases, the student of combustion theory must understand—in addition to chemical thennodynamics—the conservation equations of fluid dynamics, including transport properties and chemical kinetics. Condensed but reasonably complete treatments of these background topics are given in the appendixes. Readers unfamiliar with any of the background subjects are advised to read the appropriate appendixes before beginning Chapter 1.

The differential forms of the conservation equations derived in the appendixes for reacting mixtures of ideal gases are summarized in Section 1.1. From the macroscopic viewpoint (Appendix C), the governing equations (excluding the equation of state and the caloric equation of state) are not restricted to ideal gases. Most of the topics considered in this book involve the solutions of these equations for special flows. The forms that the equations assume for (steady-state and unsteady) one-dimensional flows in orthogonal, curvilinear coordinate systems are derived in Section 1.2, where specializations accurate for a number of combustion problems are developed. Simplified forms of the conservation equations applica...
