We study the emergence of precessing vortex core (PVC) oscillations in a swirling jet
experiment. We vary the swirl intensity while keeping the net mass flow rate fixed using a …

Depending on the reflectional and rotational symmetries of annular combustors for
aeroengines and gas turbines, self-sustained azimuthal thermoacoustic eigenmodes can be …

This paper presents an experimental study of a strongly swirling turbulent flow with the
formation of a precessing vortex core (PVC) that emerges at the outlet of a tangential swirler …

The detailed understanding of the flow-flame interaction in a swirling flame is crucial for the
study of turbine engine combustion. The phase and amplitude of the heat release rate as a …

We explore experimentally whether axisymmetry breaking can be exploited for the open-
loop control of a prototypical hydrodynamic oscillator, namely a low-density inertial jet …

This study of an externally forced, amplifier-type turbulent reacting swirling annular jet
presents a low-order model for the flow response to transverse acoustic excitation and …

This paper analyzes the flame dynamics of near LBO (lean blowoff) swirl stabilized flames,
using simultaneous OH and CH 2 O (formaldehyde) PLIF (planar laser induced …

Transversal and longitudinal combustion instabilities typically present in gas turbines and
rocket engines. It is thus important to investigate the flame responses of the two directional …

High-frequency transverse instabilities are an important concern in can combustor
configurations. In these configurations which are typically operated with multiple injectors …

To face the current situation of climate change caused by human activities, many states set
the goal to reach zero emissions of greenhouse gases by 2050 in order to contain the …
