Synchronization-based lossless non-reciprocal scattering
Tiemo Pedergnana, Abel Faure-Beaulieu, Romain Fleury +1
Breaking the reciprocity of wave propagation is a problem of fundamental interest, and a mucht-sought functionality in practical applications, both in photonics and phononics. Alth…
Dynamics of azimuthal thermoacoustic modes in imperfectly symmetric annular geometries
Thomas Indlekofer, Abel Faure-Beaulieu, James R. Dawson +1
Using a nominally symmetric annular combustor, we present experimental evidence of a predicted spontaneous symmetry breaking and an unexpected explicit symmetry breaking in the nei…
Modeling the nonlinear aeroacoustic response of a harmonically forced side branch aperture under turbulent grazing flow
Tiemo Pedergnana, Claire Bourquard, Abel Faure-Beaulieu +1
Hydrodynamic modes in the turbulent mixing layer over a cavity can constructively interact with the acoustic modes of that cavity and lead to aeroacoustic instabilities. The result…
Symmetry breaking of azimuthal waves: Slow-flow dynamics on the Bloch Sphere
Abel Faure Beaulieu, Nicolas Noiray
Depending on the reflectional and rotational symmetries of annular combustors for aeroengines and gas turbines, self-sustained azimuthal thermoacoustic eigenmodes can be standing,…
