This paper presents observations and analysis of the time-dependent behavior of a 10kW
partially pre-mixed, swirl-stabilized methane–air flame exhibiting self-excited thermo …

A series of measurements was taken on two technically premixed, swirl-stabilized methane-
air flames (at overall equivalence ratios of ϕ= 0.73 and 0.83) in an optically accessible gas …

Limit-cycle thermo-acoustic velocity coupling mechanisms are studied in a perfectly-
premixed swirl-stabilized combustor using data from 10 kHz repetition-rate stereoscopic …

A detailed analysis of the flow–flame interactions associated with acoustically coupled heat-
release rate fluctuations was performed for a 10kW, CH4/air, swirl stabilized flame in a gas …

Lean premixed combustors are highly susceptible to combustion instabilities, caused by the
coupling between heat release fluctuations and combustor acoustics. In order to predict the …

Velocity fields and flame structures of a partially premixed swirl flame in a gas turbine model
combustor are measured in axial and transverse sections using simultaneous (Stereo-) PIV …

The combined effects of velocity fluctuations (VF) and equivalence ratio fluctuations (ERF)
on thermoacoustic flame oscillations are studied experimentally in a gas turbine model …

A nozzle configuration for technically premixed gas turbine flames was operated with CH4
and air at atmospheric pressure. The flames were confined by a combustion chamber with …

This paper presents the experimental approach for determination and validation of
noncompact flame transfer functions of high-frequency, transverse combustion instabilities …

A gas turbine model combustor for partially premixed swirl flames was equipped with an
optical combustion chamber and operated with CH 4 and air at atmospheric pressure. The …
