Comparison of flamelet models for premixed turbulent combustion
For premixed turbulent combustion in the flamelet regime two different formulations are compared. One is the well-known Bray-Moss-Libby-model and the other is a recently developed model based on a field equation. By deriving a pdf transport equation for the latter, the correspondence between the two models is established. Finally, the balance equations for the mean conditioned velocity field that appear in the field equation formulation are presented.
