Identification of structures driving trailing-edge noise. Part II -- Numerical investigation
Zhenyang Yuan, Simon Demange, Kilian Oberleithner +2
The aim of the present work is to investigate the mechanisms of broadband trailing-edge noise generation to improve prediction tools and control strategies. We focus on a NACA 0012…
Identification of structures driving trailing-edge noise. Part I -- Experimental investigation
Simon Demange, Zhenyang Yuan, Simon Jekosch +4
Trailing-edge (TE) noise is the main contributor to the acoustic signature of flows over airfoils. It originates from the interaction of turbulent structures in the airfoil boundar…
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…
Linear and nonlinear receptivity mechanisms in boundary layers subject to free-stream turbulence
Diego C. P. Blanco, Ardeshir Hanifi, Dan S. Henningson +1
Large-eddy simulations of a flat-plate boundary layer, without a leading edge, subject to multiple levels of incoming free stream turbulence are considered in the present work. Wit…
Input-output analysis of the stochastic Navier-Stokes equations: application to turbulent channel flow
Gilles Tissot, André Cavalieri, Etienne Mémin
Stochastic linear modelling proposed in Tissot, Mémin & Cavalieri (J. Fluid Mech., vol. 912, 2021, A51) is based on classical conservation laws subject to a stochastic transport. O…
