Nine decades of rocket engine and gas turbine development have shown that
thermoacoustic oscillations are difficult to predict but can usually be eliminated with …

Thermoacoustic oscillations associated with transverse acoustic modes are routinely
encountered in combustion chambers. While a large literature on this topic exists for rockets …

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 …

The objective of this paper is to review the progress made in understanding the effects of
fuel composition on premixed gas turbine combustion, with a special emphasis on system …

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 …

Hydrogen is receiving increasing attention as a versatile energy vector to help accelerate
the transition to a decarbonised energy future. Gas turbines will continue to play a critical …

Accurate prediction of limit cycle oscillations resulting from combustion instability has been a
long-standing challenge. The present work uses a coupled approach to predict the limit …

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

This article describes recent progress on premixed flame dynamics interacting with acoustic
waves. Expressions are derived to determine the stability of combustors with respect to …

Abstract Ammonia (NH 3), a suitable hydrogen carrier, is regarded as one of the most
promising alternative energy sources due to its zero-carbon nature. However, the main …
