Title:
Acoustic and Intrinsic Thermoacoustic Modes of a Premixed Combustor 
Abstract:
Premixed flames are velocity sensitive, i.e. they react to a velocity perturbation at the burner mouth, say, with fluctuations in heat release rate. Unsteady heat release generates acoustic waves that travel back from the flame to the burner mouth, where they modulate the veloc- ity and thereby close an intrinsic thermoacoustic (ITA) feedback loop. The present paper demonstrates that corresponding ITA eigenmodes are in general important for the dynamics and stability of premixed combustion syste...    »
