ABSTRACT
This chapter deals with systems involving negligible transport but finite reaction rates and focuses on methods of analysis, giving a few illustrative examples; textbooks and delve more deeply into details of some of the material to be covered. Since the transport effects give rise to the most highly differentiated terms in the conservation equations, these effects will generally be unimportant provided that the gradients of the flow variables are sufficiently small. Large values of the convective and time-dependent terms help to make the transport processes negligible. The rapid transport helps to achieve conditions of uniformity, under which transport no longer is significant, and effects of finite-rate chemistry can be studied. The chapter discusses low rates of transport favor attainment of conditions under which transport phenomena are negligible. The equations governing the steady-state, quasi-one-dimensional flow of a reacting gas with negligible transport properties can easily be obtained from equations.
