Synchronization to big data: Nudging the Navier-Stokes equations for data assimilation of turbulent flows

P Clark Di Leoni, A Mazzino, L Biferale - Physical Review X, 2020 - APS
Nudging is an important data assimilation technique where partial field measurements are
used to control the evolution of a dynamical system and/or to reconstruct the entire phase …

Quantitative experimental observation of weak inertial-wave turbulence

E Monsalve, M Brunet, B Gallet, PP Cortet - Physical Review Letters, 2020 - APS

Inertial wave turbulence driven by elliptical instability

T Le Reun, B Favier, AJ Barker, M Le Bars - Physical Review Letters, 2017 - APS
The combination of elliptical deformation of streamlines and vorticity can lead to the
destabilization of any rotating flow via the elliptical instability. Such a mechanism has been …

Energy transfer in turbulence under rotation

M Buzzicotti, H Aluie, L Biferale, M Linkmann - Physical Review Fluids, 2018 - APS
It is known that rapidly rotating turbulent flows are characterized by the emergence of
simultaneous upscale and downscale energy transfer. Indeed, both numerics and …
