Lifted Flames and the Effects of Inhibitors

Combustion Science and Technology, 1995
Abstract The blowoff and liftoff characteristics of lifted turbulent diffusion flames of liquefied petroleum gas and compressed natural gas are investigated with a range of burner diameters. Uninhibited flames as well as flames inhibited by either Bromotrifluoromethane, (CF3Br known as Halon-1301), N2or Ar have been studied. The coflowing air stream is

Flame Root Dynamics and Their Role in the Stabilisation of Lifted Flames

2021
This chapter aims to provide a broad overview on the importance of lifted flames in turbulent flows with and without swirl in practical applications for energy production and propulsion. The stabilisation of lifted flames is governed by numerous physical processes that control the behaviour of the flame root or the leading edge.

Leading-Edge Flame Fluctuations in Lifted Turbulent Flames

Combustion Science and Technology, 2010
Studies are presented that examine the fluctuations in liftoff height of lifted methane flames in the presence of air coflow. At a certain jet exit velocity, a flame will lift from the burner exit and stabilize at some downstream position. The partially-premixed flame front of the lifted flame oscillates in the axial direction, with the fluctuations ...

Dynamics of Flame Lift-Off in Biogas Swirl Flames

51st AIAA/SAE/ASEE Joint Propulsion Conference, 2015
Lift-off limits and mechanism of biogas swirl flames were investigated in a gas turbine model combustor using high-repetition-rate OH* chemiluminescence and simultaneous particle image velocimetry (PIV) and OH planar laser induced fluorescence (PLIF). The biogas fuel was represented by 60% methane and 40% carbon dioxide, volumetrically. The test matrix

Lift-off Behavior and Flame Structure of Interacting Edge Flames

42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004
Laminar lifted edge flames stabilized above a five-exit slot burner are examined experimentally and numerically. In the present study, partially-premixed methane and air are used in the three-central slots to produce two neighboring edge flames. By controlling the equivalence ratios in the slots, the separation distance between the interacting edge ...
