Destructive thermoacoustic instabilities may potentially slow down significantly the ongoing
development of hydrogen combustors for decarbonizing aviation. Their early prediction …

We investigate the effect of increasing levels of hydrogen enrichment on the nonlinear
response and saturation of premixed bluff-body stabilized methane/hydrogen flames …

The main focus of this paper is to discover the link between flame macrostructure and
thermoacoustic instability in a centrally staged swirl burner. In practical combustors, the flow …

Thermoacoustic-induced vibration is a practical issue for the safe combustion operation. In
this study, we conducted experiments in a centrally-staged combustor for the realistic swirl …

We investigate the thermoacoustic response of a simple laboratory combustor where the
flame response is varied systematically by combining hydrogen enrichment with coherent …

In this paper we demonstrate how axial staging can be utilised to mitigate thermoacoustic
instabilities in a combustion system by flame redistribution. This is achieved by moving flow …

Internal flue gas recirculation (IFGR) is a commonly used low-NO x combustion technique in
industrial boilers. This study experimentally investigated the nonlinear behavior of the self …

The concept of vortex lock-in for a single circular cylinder in an oscillating flow, induced
through acoustic forcing, is revisited. Multiple cylinder diameters are investigated over a …

Short wavelength hydrodynamic perturbations excited by long wavelength acoustics can
wrinkle the front of acoustically compact flames, perturb the heat release rate, and generate …

The lean-premixed swirl combustor with slope confinement (SC) exhibits significant potential
in attenuating thermoacoustic instability compared with traditional dump confinement (DC) …
