Experiment on jet-vortex interaction for variable mutual spacing
Autor: Tobias Bölle, Vincent Brion, Marie Couliou, Pascal Molton
The interaction of a line vortex with a collinearly aligned jet is a prototypical configuration for various important applications in aeronautics. The purpose of this study is to analyze the impact of the jet flow on the kinematics and dynamics of a

Transient growth in the near wake region of the flow past a finite span wing
Autor: Navrose, Laurent Jacquin, Vincent Brion
Publikováno v: Journal of Fluid Mechanics. 866:399-430
We investigate optimal perturbation in the flow past a finite aspect ratio ($AR$) wing. The optimization is carried out in the regime where the fully developed flow is steady. Parametric study over time horizon ($T$), Reynolds number ($Re$), $AR$, an

On the linear receptivity of trailing vortices
Autor: Tobias Bölle, Vincent Brion, Denis Sipp, Jean-Christophe Robinet, Laurent Jacquin
Publikováno v: Journal of Fluid Mechanics
Journal of Fluid Mechanics, Cambridge University Press (CUP), 2020, 908, pp.29. ⟨10.1017/jfm.2020.898⟩
The present work investigates the excitation process by which free-stream disturbances are transformed into vortex-core perturbations. This problem of receptivity is modelled in terms of the resolvent in frequency space as the linear response to forc

Journal of Fluid Mechanics, Cambridge University Press (CUP), 2018, 850, pp.156-178. ⟨10.1017/jfm.2018.470⟩
A large-eddy simulation of laminar transonic buffet on an airfoil at a Mach number $M=0.735$, an angle of attack $\unicode[STIX]{x1D6FC}=4^{\circ }$, a Reynolds number $Re_{c}=3\times 10^{6}$ has been carried out. The boundary layer is laminar up to
