A PPDF combustion model that accounts for non-equilibrium and finite-rate chemistry effects in turbulent non-premixed flames (see The Laminar Flamelet Model). The corresponding node (PPDF Flamelet in the screenshot below) may be activated when an adiabatic PPDF model is selected.
This node also serves as the starting point for importing or constructing a look-up table that contains all information about chemical species and reactions needed by the PPDF flamelet model.
