Abstract:
Premixed flames respond to velocity perturbations with fluctuations in heat release rate (``thermal response''), which in turn generate acoustic perturbations (``acoustic response''). The latter may subsequently influence the velocity field in such a manner that feedback leads to self-excited thermoacoustic instability. The present paper investigates interrelations between the thermal and the acoustic responses of premix flames. The analysis is formulated such that it properly represents the und...     »
