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

“Rumble” is a self-excited combustion instability, usually occurring at the start-up of aero-
engines with fuel-spray atomizers at sub-idle and idle conditions, and exhibiting low limit …

In this study a measurement technique for determination of equivalence ratio fluctuations
from flame chemiluminescence in a kerosene-fuelled lean premixed combustor under …

This paper presents an experimental investigation of combustion instability and flame
dynamics in a laboratory-scale lean premixed prevaporized centrally staged combustor …

We experimentally investigate the nonlinear dynamics of a thermoacoustically self-excited
aero-engine combustion system featuring a turbulent swirling liquid-fueled diffusion flame in …

Low-frequency combustion dynamics of a prefilming airblast injector were experimentally
investigated in a laboratory-scale liquid-fuel combustor operated with Jet A-1 fuel and air at …

Spectral distributions of the sound pressure level (SPL) observed in a premixed, swirl
stabilized combustion test rig are scrutinized. Spectral peaks in the SPL for stable as well as …

A laboratory scale gas turbine type burner at atmospheric pressure and with air preheat was
operated with aviation kerosene Jet-A1 injected from a pressure atomiser. Self-excited …

This paper investigates low-frequency thermoacoustic instabilities of a turbulent spray flame,
a phenomenon known as 'rumble'. Based on experimental data, a network model analysis is …
