One of the important choices for achieving decarbonization goals on a large scale is the
extensive use of H 2. However, the highly reactive nature of H 2 often leads to challenges …

The implementation of advanced low-emission aircraft engine technologies and the
reduction of noise from airframe, fan, and jet exhaust have made noise contributions from an …

This paper presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

Combustion noise is becoming increasingly important as a major noise source in
aeroengines and ground based gas turbines. This is partially because advances in design …

Thermoacoustic instability in turbulent combustors is a nonlinear phenomenon resulting
from the interaction between acoustics, hydrodynamics, and the unsteady flame. Over the …

In the present work, numerical investigations are performed to study the combustion
characteristics of biogas fuel blended with hydrogen at various compositions for a non …

The transition in dynamics from low-amplitude, aperiodic, combustion noise to high-
amplitude, periodic, combustion instability in confined, combustion environments was …

The objectives of this paper are the description of azimuthal instability modes found in
annular combustion chambers using two numerical tools:(1) Large Eddy Simulation (LES) …

Thermoacoustic instability, also known as combustion instability, continues to be a problem
in the development of modern gas turbine combustors and rocket engines. Such instability is …

This paper shows that a flame can be an intrinsically unstable acoustic element. The finding
is clarified in the framework of an acoustic network model, where the flame is described by …
