The dynamics of hydrogen-enriched partially premixed methane–air flames are investigated,
focusing on the frequency response to velocity and equivalence ratio fluctuations. Large …

In a future energy system prospective, predictably dominated by (often) remote and (always)
unsteady, nondispatchable renewable power generation from solar and wind resources …

Modelling the flame response of turbulent flames via data-driven approaches is challenging
due, among others, to the presence of combustion noise. Neural network methods have …

The estimation of flame transfer functions (FTF) from time series data generated by large
eddy simulation (LES) via system identification (SI) is an important element of …

In this work, we present a parsimonious set of ordinary differential equations (ODEs),
describing with good precision and over a wide range of frequencies the linear and …

This work numerically investigates longitudinal and azimuthal thermo-acoustic instabilities in
the swirl-stabilised can-type industrial SGT-100 gas turbine combustor operated at elevated …

Thermoacoustic combustion instability is a major concern in gas turbine combustors with
hydrogen-enriched fuels. Unsteady combustion not only generates acoustic waves but it …

The flame dynamics of a kerosene spray flame is investigated under realistic operating
conditions (Tinlet≈ 850 K, pinlet≈ 30 bar). The present work evaluates the flame transfer …

Unsteady combustion generates not only acoustic waves, but also fluctuations of the burnt
gas temperature—referred to as entropy waves. These waves are convected by the mean …

This work presents a multilayer perceptron-convolutional auto-encoder (MLP-CAE) neural
network, which accurately predicts the two-dimensional flame dynamics of an acoustically …
