(Why) Jets quantise trapped acoustic modes
Brandon Yeung, Michael N. Stavropoulos, Vincent Jaunet +2
High-subsonic turbulent jets trap acoustic modes in their potential core. The modes lie in narrow frequency bands that are -wide in Strouhal number, . By studying a Mac…
Jet-edge interaction: linear and non-linear frequency-selection mechanisms
Michael N. Stavropoulos, André V. G. Cavalieri, Lutz Lesshafft +1
We consider a round turbulent jet grazing a rectangular plate angled at . Through sound pressure measurements, the tonal dynamics associated with jet-edge interaction are…
Jet-noise reduction via streak generation in the nozzle boundary layer
Filipe R. do Amaral, Petrônio A. S. Nogueira, Igor A. Maia +2
We study the hydrodynamic and acoustic fields of turbulent jets issuing from nozzles modified by the addition of cylindrical tabs on the inner surface, one diameter upstream of the…
Reactive experimental control of turbulent jets
Diego B. S. Audiffred, André V. G. Cavalieri, Igor A. Maia +2
We present an experimental study of reactive control of turbulent jets. We target axisymmetric disturbances associated with coherent structures, which are known to underpin the pea…
The effect of flight on a turbulent jet: coherent structure eduction and resolvent analysis
Igor A. Maia, Liam Heidt, Ethan Pickering +3
We study coherent structures in subsonic turbulent jets subject to a flight stream. A thorough characterisation of the effects of a flight stream on the turbulent field was recentl…
Ambiguity in mean-flow-based linear analysis
U. Karban, B. Bugeat, E. Martini +6
Linearisation of the Navier-Stokes equations about the mean of a turbulent flow forms the foundation of popular models for energy amplification and coherent structures, including r…
