Combustion instability is a serious problem limiting the operating envelope of present day
gas turbine systems using a lean premixed combustion strategy. Gas turbine combustors …

The impact of premixer swirl number, S, and overall fuel equivalence ratio, Φ, on the stability
of a model swirl-stabilized, lean-premixed gas turbine combustor has been numerically …

This paper reports an experimental investigation of a non-reacting turbulent swirling flow in
a practical vortex combustor. The flow was examined for the conditions characteristic of the …

This paper first reviews recent ideas that explain why swirl has a strong stabilizing effect on
a flame. Then some measurements are discussed that were obtained using a complex gas …

Two main types of flow pattern occur in certain types of swirl burner for various Reynolds
numbers, mixture ratios and axial fuel entry. They are as follows:(a) Flows which contain a …

Combustion instabilities have long been a source of significant problems for premixed
combustion systems 1-7. These instabilities occur when unsteady heat release couples with …

Nowadays, almost all state of the art gas turbines employ swirl-stabilized combustors for
flame stabilization. A strong swirl is imparted on a jet that emanates into the combustion …

The effect of premixer-induced inlet swirl on the stability of a model swirl-stabilized, lean-
premixed gas turbine combustor has been numerically investigated using the large-eddy …

This paper reviews the occurrence of the precessing vortex core (PVC) and other
instabilities, which occur in, swirl combustion systems whilst identifying mechanisms, which …

ABSTRACT A study of the destabilising effect of self-exited bulk-mode oscillations on the
shape and size of recirculation zones has been carried out in a swirl burner/furnace. Cycle …
