On the stability of the laminar boundary layer beneath a Stokes wave
Francesco Fedele
The linear stability of the laminar boundary layer flow of a Stokes wave in deep waters is investigated by means of a 'momentary' criterion of instability for unsteady flows (Blond…
On the kurtosis of deep-water gravity waves
Francesco Fedele
In this paper, we revisit Janssen's (2003) formulation for the dynamic excess kurtosis of weakly nonlinear gravity waves at deep water. For narrowband directional spectra, the form…
Symmetry reduction of turbulent pipe flows
Francesco Fedele, Ozeair Abessi, Philip Roberts
We propose and apply a Fourier-based symmetry reduction scheme to remove, or quotient, the streamwise translation symmetry of Laser-Induced-Fluorescence measurements of turbulent p…
Hopf fibrations for turbulent pipe flows
F. Fedele, O. Abessi, P. J. Roberts
We propose a generalization of Hopf fibrations to quotient the streamwise translation symmetry of turbulent pipe flows viewed as dynamical systems. In particular, we exploit the ge…
On certain properties of the compact Zakharov equation
Francesco Fedele
Long-time evolution of a weakly perturbed wavetrain near the modulational instability threshold is investigated within the framework of the compact Zakharov equation for unidirecti…
Vortexons in axisymmetric Poiseuille pipe flows
Francesco Fedele, Denys Dutykh
We present a study on the nonlinear dynamics of small long-wave disturbances to the laminar state in non-rotating axisymmetric Poiseuille pipe flows. At high Reynolds numbers, the…
