ABSTRACT
This chapter discusses the differential forms of the conservation equations derived in the appendixes for reacting mixtures of ideal gases. It describes the forms that the equa-tions assume for one-dimensional flows in orthogonal, curvilinear coordinate systems. The chapter explores simplified forms of the conservation equations applicable to steady-state problems in three dimensions. It also describes the flow for most of the combustion processes that have been analyzed satisfactorily. Since combustion problems requiring theoretical analysis are primarily concerned with the flow of reacting and diffusing gases, the student of com-bustion theory must understand—in addition to chemical thennodynamics—the conservation equations of fluid dynamics, including transport properties and chemical kinetics. In many steady-state combustion problems, body forces are negligible and a consequent simplification in the energy equation is possible. The chapter also presents an overview of the key concepts discussed in this book.
