Non-linearities in the thermoacoustic response of a premixed swirl burner [PDF]
, 2009 PhDLean premixed combustion remains one of the simplest and most effective methods of reducing NOx emissions in industrial gas turbines. Lean premixed flames are however prone to an undesirable side effect known as combustion instability, reducing ...

Non-Premixed Filtered Tabulated Chemistry for LES: Evaluation on Sandia Flames D and E
Fuels, 2022 The non-premixed filtered tabulated chemistry for large eddy simulations employs numerical filtering to resolve a thin flame front on practical LES numerical grids. The flame structure is modified to be coherent with the domain discretization.
