## 9.11. Flamelet Libraries

The mixture fraction based combustion models in ANSYS CFX (PDF Flamelet, Burning Velocity Model and Extended Coherent Flame Model) require a flamelet library that defines the burnt mixture composition as a function of the combustion scalars solved.

The following topics will be discussed:

- Loading Flamelet Libraries

- Flamelet Library (FLL) File Format

- Stoichiometric Mixture Fraction

- Laminar Burning Velocity

It is possible to use flamelet libraries, provided that the appropriate file format is used. For details, see Flamelet Library (FLL) File Format.
