Averaging of thermoacoustic azimuthal instabilities
Giulio Ghirardo, Francesco Gant
We consider the acoustic flow field of rotationally symmetric systems, like an annular combustor and the flow in a round duct, in absence of a mean azimuthal flow field. We focus o…

Background noise pushes azimuthal instabilities away from spinning states
Giulio Ghirardo, Francesco Gant
Azimuthal instabilities occur in rotationally symmetric systems, either as spinning (rotating) waves or standing waves. We make use of a novel ansatz to derive a differential equat…
