Abstract
Laminar flamelet library was built up with steady state laminar stretched diffusion flames, indexed by the mixture fraction-progress variable. Then the β PDF of mixture fraction and first-order conditional PDF of the progress variable were employed to generate the mean turbulent flamelet library. By adding the library looking up and solving sections to OpenFOAM, a turbulent combustion solver named ZCFoam was developed based on RANS. A typical turbulent methane/air partially premixed jet flame was studied. The computational results indicate that the FPV approach could satisfactorily predict the flame structure, temperature and species concentration fields.
