In addition to the volumetric and surface reactions described in the previous sections, you can also use FLUENT to solve a species mixing problem without reactions. The species transport equations that FLUENT will solve are described in Section 14.1.1, and the procedure you will follow to set up the non-reacting species transport problem is the same as that described in Sections 14.1.2- 14.1.6, with some simplifications.
The basic steps are listed below:
Define Models Species Transport & Reaction...
See Section 14.1.2 for information about the mixture material concept, and Section 14.1.3 for more details about using the Species Model panel.
Mixture properties include the following:
See Section 14.1.4 for details.
No special solution procedures are usually required for a non-reacting species transport calculation. Upon completion of the calculation, you can display or report the following quantities:
These variables are contained in the Species... and Properties... categories of the variable selection drop-down list that appears in postprocessing panels. See Chapter 30 for a complete list of flow variables, field functions, and their definitions. Chapters 28 and 29 explain how to generate graphics displays and reports of data.
