The effect of hydrogen enrichment, flame-flame interaction, confinement, and asymmetry on the acoustic response of a model can combustor
Æsøy, Eirik; Indlekofer, Thomas; Gant, Francesco; Cuquel, Alexis; Bothien, Mirko R.; Dawson, James Richard (Peer reviewed; Journal article, 2022)To maximise power density practical gas turbine combustion systems have several injectors which can lead to complex interactions between flames. However, our knowledge about the effect of flame-flame interactions on the ... -
The influence of hydrogen on the stability of a perfectly premixed combustor
Aguilar, Jose; Æsøy, Eirik; Dawson, James Richard (Journal article; Peer reviewed, 2022) -
Systematic modulation of the flame transfer function and its effect on thermoacoustic stability
Æsøy, Eirik; Dawson, James Richard; Moeck, Jonas (Journal article; Peer reviewed, 2024)We investigate the thermoacoustic response of a simple laboratory combustor where the flame response is varied systematically by combining hydrogen enrichment with coherent vortex shedding to introduce modulations in the ... -
Tailoring the gain and phase of the flame transfer function through targeted convective-acoustic interference
Æsøy, Eirik; Nygård, Håkon Tormodsen; Worth, Nicholas; Dawson, James Richard (Peer reviewed; Journal article, 2022)This paper investigates how targeted interference between two well characterized sources of hydrodynamic disturbances can modify the response of premixed bluff body stabilised flames with and without swirl. We introduce ...
