In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple
with acoustic pressure oscillations. If the heat release is sufficiently in phase with the …

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

Thermoacoustic systems can oscillate self-excitedly, and often non-periodically, owing to
coupling between unsteady heat release and acoustic waves. We study a slot-stabilized two …

Flame-acoustic interactions are witnessed in the context of combustion instability in gas
turbine combustors and other propulsion devices, such as rockets, besides confined …

Unlike hydrocarbon fuel, ammonia (NH 3) is an alternative but promising carbon-free
renewable fuel. The utilization of NH 3 as an energy resource can effectively reduce …

Hydrogen-enrichment of conventional natural gas mixtures is an actively-explored strategy
for reducing pollutant emissions from combustion. This study investigates the effect of …

This paper presents an experimental investigation of combustion instabilities for a laminar
premixed flame stabilized on a slot burner. For certain operating conditions, the system …

In an acoustic cavity with a heat source, such as a flame in a gas turbine, the thermal energy
of the heat source can be converted into acoustic energy, which may generate a loud …

As a promising strategy to mitigate carbon emissions, hydrogen enrichment of conventional
fuels is gaining increasing interest, but can lead to increased propensity to damaging …

Many thermoacoustic systems exhibit rich nonlinear behaviour. Recent studies show that
this nonlinear dynamics can be well captured by low-order time domain models that couple …
