Self-sustained combustion instabilities are one of the most plaguing challenges and
problems in lean-conditioned propulsion and land-based engine systems, such as rocket …

Thermoacoustic combustion instability is one of the most challenging operational issues in
several high-performance, low-emissions combustion technologies, including gas turbines …

Lean premixed combustion chambers are susceptible to combustion instabilities arising
from the coupling between the heat release rate perturbations and the acoustic …

Combustion instability frequently occurs in propulsion and power generation systems. It is
characterized by large-amplitude acoustic oscillations leading to undesirable …

Thermoacoustic phenomena generated inadvertently during combustion, and those
produced by heating and cooling material to generate a temperature gradient, have mostly …

The fuel composition effects of H 2/CH 4 syngas in a partially premixed model combustor
(PP-MC) were examined for the unique phenomenon of combustion instability (CI) …

Considerable research and development efforts are required to meet the targets of future
gas turbine technologies in terms of performance, emissions, and operational flexibility. One …

We experimentally study the nonlinear dynamics of a self-excited thermoacoustic system
subjected to acoustic forcing. Our aim is to relate these dynamics to the behavior of universal …

In many combustion devices, strong self-excited flow oscillations can arise from feedback
between unsteady heat release and acoustics, resulting in increased vibration and pollutant …

In this paper, the fuel composition effects of H 2/CO/CH 4 syngas (0–100% for each
component gas) on the self-excited high multi-mode (mainly the 3rd and 4th with their …
