Abstract The influence of Intrinsic Thermoacoustic (ITA) feedback on the combustion noise
spectrum produced by a confined, turbulent, premixed, swirl flame is investigated. The …

The combustion instability of a partially premixed swirl burner is investigated by
experimental tests and numerical modeling. The experimental results show that the …

We present a two-step optimization (TSO) framework, which uses the pressure data of an
unstable combustion process to estimate the complex-valued flame transfer function (FTF) …

We present two MATLAB toolboxes, provided as open-source code, that expand the
capabilities of the Control System Toolbox to large-scale models. sss allows the definition …

In this paper, non-intrusive polynomial chaos expansion (NIPCE) is used for forward
uncertainty quantification and sensitivity analysis of thermoacoustic stability of two premixed …

The combustion noise produced by a confined, turbulent, premixed swirl burner is predicted
with large-eddy simulation of compressible, reacting flow. Characteristics-based state-space …

This study assesses and compares two alternative approaches to determine the acoustic
scattering matrix of a premixed turbulent swirl combustor:(1) The acoustic scattering matrix …

Abstract The Large Eddy Simulation/System Identification (LES/SI) approach allows to
deduce a flame transfer function (FTF) from LES of turbulent reacting flow: Time series of …

Nonintrusive polynomial chaos expansion (NIPCE) is used to quantify the impact of
uncertainties in operating conditions on the flame transfer function (FTF) of a premixed …

The Large Eddy Simulation/System Identification (LES/SI) approach is a general and
efficient numerical method for deducing a Flame Transfer Function (FTF) from the LES of …
