7. Species Transport and Finite-Rate Chemistry

ANSYS FLUENT can model the mixing and transport of chemical species by solving conservation equations describing convection, diffusion, and reaction sources for each component species. Multiple simultaneous chemical reactions can be modeled, with reactions occurring in the bulk phase (volumetric reactions) and/or on wall or particle surfaces, and in the porous region. Species transport modeling capabilities, both with and without reactions, are described in this chapter.

Note that you may also want to consider modeling your turbulent reacting flame using the mixture fraction approach (for non-premixed systems, described in Chapter  8), the reaction progress variable approach (for premixed systems, described in Chapter  9), the partially premixed approach (described in Chapter  10), or the composition PDF Transport approach (described in Chapter  11). Modeling multiphase species transport and finite-rate chemistry can be found in Chapter  16.

For more information about using these models in ANSYS FLUENT, see this chapter in the separate User's Guide.
