Flame Transfer Function Measurement of a Hydrogen-Blended Sequential Combustor
Bayu Dharmaputra, Pushkin Nagpure, Matteo Impagnatiello +1
The flame transfer function (FTF) relates acoustic perturbations and the coherent heat release rate response. This frequency-dependent function governs the thermoacoustic stability…
