Differential Conservation Principles

Abstract

As shown in Chapter 6, the integral equations provide global information about the domain of interest, such as global balances or average values of the fluid variables. Sometimes, however, more detailed information about the fluid field is required, like local temperature distributions or concentration gradients. This kind of information can be provided by the differential form of the transport equations.

The equations derived in this chapter stem from those of Chapter 6 and therefore apply for multicomponent systems with the same body force for all chemical species. For the transport equations where the body force depends on the species, see Appendix I.
