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…

Thermoacoustic Stabilization of a Sequential Combustor with Ultra-low-power Nanosecond Repetitively Pulsed Discharges
Bayu Dharmaputra, Sergey Shcherbanev, Bruno Schuermans +1
This study demonstrates the stabilization of a sequential combustor with Nanosecond Repetitively Pulsed Discharges (NRPD). A constant pressure sequential combustor offers key advan…
