## 7.9. Burning Velocity Model (Premixed or Partially Premixed)

The model for premixed or partially premixed combustion can be split into two independent parts:

- Model for the progress of the global reaction: Burning Velocity Model (BVM), also called Turbulent Flame Closure (TFC)

- Model for the composition of the reacted and non-reacted fractions of the fluid: Laminar Flamelet with PDF

The mass fractions in the non-reacted fraction of the fluid, , are obtained by linear blending of fuel and oxidizer compositions. The species mass fractions in the burned fraction of the fluid, , are computed by applying the Flamelet model.
