Excitation of the precessing vortex core by active flow control to suppress thermoacoustic instabilities in swirl flames

Lückoff, Finn ; Oberleithner, Kilian (2019-07-04)

In this study, we apply periodic flow excitation of the precessing vortex core at the centerbody of a swirl-stabilized combustor to investigate the impact of the precessing vortex core on flame shape, flame dynamics, and especially thermoacoustic instabilities. The current control scheme is based on results from linear stability theory that determine the precessing vortex core as a global hydro...
