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…
Train yourself: self-compressing reduced-order models of turbulent flows
Ian Addison-Smith, Igor A. Maia, Benjamin Herrmann +1
Reduced-order models (ROMs) of turbulent flows based on Galerkin projection often require many degrees of freedom to resolve the dynamics of the turbulence, or simulation data to o…
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…
Turbulence suppression in plane Couette flow using reduced-order models
Igor A. Maia, André V. G. Cavalieri
We explore a reduced-order model (ROM) of plane Couette flow with a view to performing turbulence control. The ROM is derived through Galerkin projections of the incompressible Nav…
Experimental control of Tollmien-Schlichting waves using the Wiener-Hopf formalism
Diego B. S. Audiffred, André V. G. Cavalieri, Pedro P. C. Brito +1
Reactive flow control has been shown as a promising tool to improve, among other aspects, the aerodynamic characteristics of an aircraft. This paper focuses on the use of reactive…
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…
