Improvement of Laminar Lifted Flame Stability Excited by High-Frequency Acoustic Oscillation
A high-frequency (20kHz) standing wave was applied to the unburned mixture upstream of a methane-air lifted jet flame using a bolt-clamped Langevin transducer (BLT) to improve stability.

Effect of a single nanosecond pulsed discharge on a flat methane–air flame
Successful implementation of plasma-assisted combustion in applied thermal processes heavily relies on how the plasma can be formed as it interacts with the reactive flow and what the effects are of such a plasma on the combustion process.

Lift-off and blowoff of a diffusion flame between parallel streams of fuel and air [PDF]
A numerical analysis is presented to describe the liftoff and blowoff of a diffusion flame in the mixing layer between two parallel streams of fuel (mainly methane diluted with nitrogen) and air emerging from porous walls.

Lifted Partially Premixed Flames in Microgravity [PDF]
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.

Comparison of Combustion Models for Lifted Hydrogen Flames within RANS Framework
Within the framework of a Reynolds averaged numerical simulation (RANS) methodology for modeling turbulence, a comparative numerical study of turbulent lifted H2/N2 flames is presented.

Experimental Investigation of Flame Anchoring Behavior in a LOX/LNG Rocket Combustor
Hot fire tests of a multi-injector research combustor were performed with liquid-oxygen and liquefied-natural-gas (LOX/LNG) propellants at chamber pressures from 30 up to 67 bar, hence at conditions similar to an upper stage rocket engine.

Modelling of turbulent lifted jet flames using flamelets: a priori assessment and a posteriori validation [PDF]
This study focuses on the modelling of turbulent lifted jet flames using flamelets and presumed PDF approach with interests on both flame lift-off height and flame brush structure.
