The unsteady response of a flame to acoustic or flow perturbations plays a crucial role in
thermoacoustic combustion instability. The majority of studies on this subject presents and …

The present work introduces an annular combustion chamber operated at intermediate
pressures. The combustor is operated with CH 4-H 2 blends leading to a variety of azimuthal …

Self-excited combustion instabilities are characterized by large-amplitude limit cycle
oscillations of thermodynamic properties such as pressure, velocity and heat release. In …

This paper investigates the simplifying assumptions used for deriving low order models of
thermoacoustic instabilities and thermoacoustic intermittency in turbulent combustor. These …

Combustion instability has been a common problem accompanied with the low NO x
emission technologies for the industrial premixed burner. The effects of flue gas recirculation …

In this study, the heat release rate (HRR) response during self-excited azimuthal
thermoacoustic instabilities in a pressurized annular combustor is investigated for …

Destructive thermoacoustic instabilities may potentially slow down significantly the ongoing
development of hydrogen combustors for decarbonizing aviation. Their early prediction …

In this paper the nonlinear dynamics of the pure Intrinsic Thermo-Acoustic (ITA) modes are
experimentally investigated for burner stabilized premixed flames by decoupling them from …

This paper examines and compares the commonly used machine learning algorithms in
their performance in interpolation and extrapolation of flame describing function (FDFs) …

This paper demonstrates the ability of recurrent neural networks (RNNs) to predict the linear
and the nonlinear response of a premixed laminar flame to incoming velocity perturbations …
