F.2. Table Lookup Option

The second option for flame speeds is the Table Lookup option. Ansys Forte comes installed with pre-built laminar flame-speed tables for five common gasoline and natural-gas fuel-surrogate components that can be used with the Table Lookup option. These files can be located in the data directory of the Ansys Forte installation:

ANSYS Inc\vXXX\reaction\forte.win64\data\flamespeed_libraries

where XXX is the Ansys version.

These tables can be considered as templates when you want to build your own laminar flame-speed tables. The conditions covered for the built-in tables included as part of the Table Lookup option are summarized in Table 3: Mixture conditions covered by the built-in laminar flame-speed tables available in the Table Lookup option. More detailed information regarding the table's parameters is given in Flame-Speed Table Editor.
