Abstract: Lean premixed combustion is the state-of-the-art technology to achieve ultra low NOx emissions in stationary gas turbines. However, lean premixed flames are susceptible to thermoacoustic instabilities, lean blowout, and ...

Abstract: Abstract. Gas turbine combustors rely on swirling flows for flame stabilization. The flow's swirl number is herein characterized by the burner's swirler geometry. In addition to stability, swirl represents an important ...
