Non-Premixed Filtered Tabulated Chemistry: Filtered Flame Modeling of Diffusion Flames

The flame front filtering is a well-known strategy in turbulent premixed combustion. An extension of this approach for the non-premixed combustion context has been proposed by means directly counterflow diffusion flamelets. Promising results were obtained filtered tabulated chemistry formalism on 1-D and 2-D unresolved configurations. present paper demonstrates soundness 3-D real laminar coflow flame. model are compared against direct fully resolved showing that adequately describes underlying physics. study reveals importance one-dimensional flamelet hypothesis, so activation under condition ensured sensor. consistent coupling between sensor retrieves lift-off satisfactorily predicts profile due to process.
