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…

Modal-based generalised quasilinear approximations for turbulent plane Couette flow
Igor A. Maia, André V. G. Cavalieri
We study generalised quasilinear (GQL) approximations applied to turbulent plane Couette flow. The GQL framework is explored in conjunction with a Galerkin reduced-order model (ROM…

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…
