Abstract Direct Numerical Simulations (DNS) are performed to investigate the process of
spontaneous ignition of hydrogen flames at laminar, turbulent, adiabatic and non-adiabatic …

A three-dimensional direct numerical simulation (DNS) is performed for a turbulent hydrogen-
air flame, represented with detailed chemistry, stabilized in a model gas-turbine combustor …

This numerical study investigates the combustion modes in the second stage of a sequential
combustor at atmospheric and high pressure. The sequential burner (SB) features a mixing …

This numerical study investigates the linear and non-linear flame dynamics in the second
stage of a sequential combustor, with methane fuel injection into vitiated hot gas. It focuses …

We address the problem of turbulent spontaneous ignition vs. deflagration propagating
against a mean residence time gradient, particularly relevant to the stabilization of quasi …

Thermoacoustics in modern gas turbines is often accompanied by lean premixed
combustion. A flame transfer function (FTF) is an important quantity for quantifying …

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 …

We discuss the statistics of acoustic pressure of thermoacoustic oscillations, either axial or
azimuthal in nature. We derive a model where the describing functions of the fluctuating heat …

Lean premix technology is widely spread in gas turbine combustion systems, allowing
modern power plants to fulfill very stringent emission targets. These systems are however …

Numerical simulations of laminar premixed flames burning hydrogen and methane in
spontaneous ignition mode are performed by harmonically exciting the reactants' …
