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 …

Numerical simulations were used to characterise the non-linear response of a turbulent
premixed flame to acoustic velocity fluctuations. The test flame simulated was the bluff body …

This paper analyzes the forced response of swirl-stabilized lean-premixed flames to high-
amplitude acoustic forcing in a laboratory-scale stratified burner operated with CH4 and air …

Acoustically forced lean premixed turbulent bluff-body stabilized flames are investigated
using turbulent combustion CFD. The calculations simulate aspects of the experimental …

Stereoscopic particle image velocimetry and planar laser induced fluorescence
measurements of hydroxyl radical are simultaneously applied to measure, respectively, local …

We construct a low-order thermoacoustic network model that contains the most influential
physical mechanisms of a thermoacoustic system. We apply it to a laboratory-scale …

Turbulent lean premixed combustion has high potentials for the development of modern low
nitrogen oxide gas turbines. However, it renders the combustor prone to combustion …

This paper describes the simultaneous application of time-sequenced laser-induced
fluorescence imaging of OH radicals and stereoscopic particle image velocimetry for …

Numerical simulations aid combustor design to avoid and reduce thermoacoustic
oscillations. Non-linear heat release rate estimation and its modelling are essential for the …

The response of a lean premixed flame subjected to acoustic perturbations is a complex
phenomenon that depends highly on the type of flame and the operating conditions. Swirl …
