For flame stabilization, burner systems are usually equipped with swirlers which incite a
defined air rotation, quantified by the swirl number. In consequence, the swirl number, which …

Swirling flame dynamics is investigated using a radial swirler equipped with movable
blades. This device allows to continuously change the swirl number and to examine various …

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 …

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

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 …
