Numerical study of ignition and combustion of hydrogen-enriched methane in a sequential combustor
Matteo Impagnatiello, Quentin Malé, Nicolas Noiray
Ignition and combustion behavior in the second stage of a sequential combustor are investigated numerically at atmospheric pressure for pure CH4 fueling and for a CH4/H2 fuel blend…
Steady State Statistics of Emergent Patterns in a Ring of Oscillators
Tiemo Pedergnana, Nicolas Noiray
Networks of coupled nonlinear oscillators model a broad class of physical, chemical and biological systems. Understanding emergent patterns in such networks is an ongoing effort wi…
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…
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,…
Stabilization of acoustic modes using Helmholtz and Quarter-Wave resonators tuned at exceptional points
Claire Bourquard, Nicolas Noiray
Acoustic dampers are efficient and cost-effective means for suppressing thermoacoustic instabilities in combustion chambers. However, their design and the choice of their purging a…
Bifurcation Dodge: Avoidance of a Thermoacoustic Instability under Transient Operation
Giacomo Bonciolini, Nicolas Noiray
Varying one of the governing parameters of a dynamical system may lead to a critical transition, where the new stable state is undesirable. In some cases, there is only a limited r…
