Response of a laminar premixed flame to flow oscillations: A kinematic model and thermoacoustic instability results
Combustion instability is a resonance phenomenon that arises due to the coupling between the system acoustics and the unsteady heat release. The constructive feedback between the two processes, whichExpand
