Identification of flame transfer functions during transient operation
INTER-NOISE and NOISE-CON Congress and Conference ProceedingsPredicting thermoacoustic instabilities requires knowledge of the flame response to acoustic perturbations, which is characterized by the Impulse Response Function. Obtaining stability maps across an extensive parameter space is prohibitively costly with existing methods, both experimentally and numerically, as the data records must be obtained ...

The Effect of Chemical Kinetic Mechanisms on the Flame Transfer Function
Proceedings of Global Power & Propulsion SocietyThis paper reports the investigation of the effect of chemical kinetic mechanisms on the thermoacoustic behaviour of a premixed combustor test rig. This was done by exploring the flame transfer function (FTF) of three chemical kinetic mechanisms; a global (6 species, 2 reaction) mechanism, a reduced (19 species, 55 reaction) mechanism and a detailed ...

Measuring the flame transfer function of turbulent non-premixed syngas flames
2006Syngas is a fuel, obtained from gasification of coal or other heavy hydrocarbons. It is used to fire gas turbines. Syngas consists of hydrogen (H2), carbon monoxide (CO) and some inert components like nitrogen (N2) or water vapour (H2O). Sometimes methane (CH4) is present.
