The dynamics of premixed confined swirling flames is investigated by examining their
response to incident velocity perturbations. A generalized transfer function designated as …

Thermoacoustic combustion instability is one of the most challenging operational issues in
several high-performance, low-emissions combustion technologies, including gas turbines …

The present paper describes a methodology to improve the accuracy of prediction of the
eigenfrequencies and growth rates of self-induced instabilities and demonstrates its …

Thermoacoustic systems can oscillate self-excitedly, and often non-periodically, owing to
coupling between unsteady heat release and acoustic waves. We study a slot-stabilized two …

The wake characteristics of bluff-body-stabilized flames are a strong function of the density
ratio across the flame and the relative offset between the flame and shear layer. This paper …

The crux of the technical issues facing the development of hydrogen gas turbine engines is
the problem of how to enable low NOx, low dynamics combustor operations without …

Thermoacoustic systems with a turbulent reactive flow, prevalent in the fields of power and
propulsion, are highly susceptible to oscillatory instabilities. Recent studies showed that …

Gas turbine engines are prone to the phenomenon of thermoacoustic instability, which is
highly detrimental to their components. Recently, in turbulent combustors, it was observed …

The dynamics of a turbulent premixed confined swirling flame is investigated using large
eddy simulation. The flame response is determined by introducing an external acoustic …

This paper deals with the response of swirling flames submitted to acoustic velocity
disturbances when the rotation of the flow is produced by an axial or a radial swirler. The …
