One of the important choices for achieving decarbonization goals on a large scale is the
extensive use of H 2. However, the highly reactive nature of H 2 often leads to challenges …

This paper presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

The precessing vortex core (PVC) is a coherent flow structure that is often encountered in
swirling flows in gas turbine (GT) combustors. In some swirl combustors, it has been …

In this paper, we report results from an experimental investigation on transitions in the
average flame shape (or microstructure) under acoustically coupled and uncoupled …

In this paper, a novel dual-fuel, dual-swirl burner is presented and its potential to mitigate
thermoacoustic coupling for ammonia-hydrogen-air flames is explored. The key feature of …

The lift-off mechanism of swirl stabilized premixed flames was investigated using high
repetition rate OH planar laser induced fluorescence (PLIF), particle image velocimetry …

This report deals with an experimental and analytical study of the occurrence of self-excited
hydrodynamic instabilities in swirling combustor flows. Different flow field types are …

Topology transitions of swirl-stabilized flames in a cylindrical combustion chamber are
analyzed for lean CH 4/H 2/air combustible mixtures. It is demonstrated that when the tip of a …

The flame describing function is a valuable tool for the limit-cycle prediction of
thermoacoustic instabilities, which are frequently observed in modern gas turbines. In these …

The huge amounts of accumulated unclaimed liquid hydrocarbon waste (waste from oil
production and oil refining, etc.) determine the prospects for their involvement in energy …
