DOI: 10.1016/j.ast.2021.106696
Abstract: Abstract This paper investigates the intrinsic thermoacoustic (ITA) feedback and its possible interaction with the cavity acoustic resonance in swirling flame combustors under the configuration of axisymmetric perturbations. The dynamics of acoustic-vortical-entropic perturbations due to… read more here.
