Features of the flame transfer function (FTF) are characterized for turbulent, non-swirled,
bluff body stabilized “M” flames for different hydrogen and methane blends including pure …

We investigate the occurrence and source of modulations in the gain and phase of flame
transfer functions (FTF) measured in perfectly premixed, bluff body stabilized CH 4/H 2 and …

The flame transfer function (FTF) and flame dynamics of a highly swirled, closely confined,
premixed flame is studied over a wide range of equivalence ratios and bulk velocities at a …

In this study, an in-house developed fully compressible solver utilizing high-order numerical
discretization schemes is used to study the effects of swirl intensity on thermoacoustic …

The frequency response of premixed swirled flames is investigated by comparing their
Transfer Function (FTF) between velocity and heat release rate fluctuations. The …

The frequency response of a confined premixed swirled flame is explored experimentally
through the use of describing functions that depend on both the forcing frequency and the …

This paper presents an analysis of the unsteady heat release rate response of industrially
relevant axisymmetric premixed flames to harmonic velocity perturbations. The heat release …

Abstract The Flame Transfer Function (FTF) and flame dynamics of a single, highly swirled,
closely confined, premixed flame is studied over a wide range of operating conditions at a …

Thermoacoustic instabilities have become an increasingly relevant issue in the search for
lower emissions in gas turbines, both for power production and transportation. Adoption of …

Gas turbines have an important role in modern engineering and the development of low
emission propulsion systems is a multi-dimensional challenge with no single solution …
