Lifted Partially Premixed Flames in Microgravity [PDF]
42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004 Lifted Double and Triple flames are established in the UIC-NASA Partially Premixed microgravity rig. The flames examined in this paper are established above a coannular burner because its axisymmetric geometry allows for future implementation of other non-intrusive optical diagnostic techniques easily.

A novel diffusion flux modeling for laminar premixed flame simulation with OpenFOAM
Results in Engineering, 2023 In this study, we developed a mass diffusion coefficient model for premixed combustion to reduce the computational time, in mixture-averaged diffusivities to serve as a microcomputer resource.

Modelling of premixed combustion in a gas turbine [PDF]
, 1998 Three steady state combustion models, two turbulence models and a model for tK'6 prediction of NO., were implemented and investigated on a simple backward facing step experiment as well as an experimental lean prevaporised premixed (LPP) combustor ...

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 ...

Flame structure simulation in a methane/air coflow partially premixed burner
Revista Facultad de Ingeniería Universidad de Antioquia, 2014 The effect of the equivalence ratio on the partially premixed methane / air laminar flame structure, in a coflow atmospheric burner was simulated. Three equivalence ratios were studied (Φ=1.6, Φ=2.0, Φ=3.5) keeping constant the released energy.
