During the design and testing process of swirl-stabilized combustors, it is often impractical to
maintain identical outlet boundary conditions. Furthermore, it is a common practice to …

The most common and reliable technique used for flame stabilization of industrial
combustors with high thermal loads is the application of strongly swirling flows. In addition to …

Swirling flows are commonly used for flame stabilization in gas turbine combustors, which
are hence equipped with suitable swirler units. In these units the air rotation, quantified by …

Combustion instabilities represent a long known problem in combustion technology. The
complex interactions between acoustics and turbulent swirling flames are not fully …

There has been increased demand in recent years for low NOx gas turbines to meet
stringent emission goals by operating in a lean, premixed combustion mode. Unfortunately …

The flame structure and the limits of operation of a lean premixed swirl flame were
experimentally investigated under piloted and nonpiloted conditions. Flame stabilization and …

This paper examines the manner in which heat release resulting from premixed combustion
alters the nature of near-critical, axisymmetric, swirling flow in a straight circular pipe …

Combustion instabilities are an undesired phenomenon in premix burners, leading to
vibrations and potential flame problems such as lift-off or flashback. The combustion stability …

The present work addresses unsteady flame dynamics in a lean-premixed swirl-stabilized
combustor, with attention focused on the transition of flame structure from a stable to an …
