Flowfield-flame structure interactions in an oscillating swirl flame [PDF]

Combustion, Explosion, and Shock Waves, 2009
A swirling methane-air diffusion flame at atmospheric pressure is stabilized in a gas turbine model combustor with good optical access. The investigated flame with a thermal power of 10 kW and an overall equivalence ratio of 0.75 exhibits pronounced thermoacoustic oscillations at a frequency of 295 Hz.
