Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2019)A comprehensive study of the two-dimensional incompressible shear-driven flow in an open square cavity is carried out. Two successive bifurcations lead to two limit cycles with different frequencies and different numbers ...
-
Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2020)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 ...
-
Article dans une revue avec comité de lecture(American Physical Society, 2020)The modal and nonmodal linear stability of a stably stratified Blasius boundary layer flow, composed of a velocity and a thermal boundary layer, is investigated. The temporal and spatial linear stability of such flow is ...
-
Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2015)The structure of zero-pressure-gradient compressible turbulent boundary layers is analysed using the tools of optimal transient growth theory. The approach relies on the extension to compressible flows of the theoretical ...
-
Article dans une revue avec comité de lecture(Acoustical Society of America, 2015)Noise generation by flows is modeled using a pressure wavepacket to excite the acoustic medium via a boundary condition of the homogeneous wave equation. The pressure wavepacket is a generic representation of the flow ...
-
Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2015)A simple approach is described for computing spatially extended, weakly nonlinear optimal disturbances, suitable for maintaining a disturbance-regeneration cycle in a simple shear flow. Weakly nonlinear optimals, computed ...

Chapitre d'ouvrage scientifique(Springer, 2017)Turbulent flows of industrial interest are often dominated by large turbulent structures. A typical example is provided by launcher base flows, combining one or more extended and interacting separated regions with strong ...
