Quasi-two-dimensional turbulence

A Alexakis - Reviews of Modern Plasma Physics, 2023 - Springer
Many fluid-dynamical systems met in nature are quasi-two-dimensional: they are
constrained to evolve in approximately two dimensions with little or no variation along the …

Core eigenmodes and their impact on the Earth's rotation

SA Triana, M Dumberry, D Cébron, J Vidal, A Trinh… - Surveys in …, 2022 - Springer
Abstract Changes in the Earth's rotation are deeply connected to fluid dynamical processes
in the outer core. This connection can be explored by studying the associated Earth …

Quantitative experimental observation of weak inertial-wave turbulence

E Monsalve, M Brunet, B Gallet, PP Cortet - Physical Review Letters, 2020 - APS
We report the quantitative experimental observation of the weak inertial-wave turbulence
regime of rotating turbulence. We produce a statistically steady homogeneous turbulent flow …

ensemble of internal gravity waves which approaches statistical homogeneity and …

Nonlinear regimes of inertial wave attractors generated by a precessing lid: Zonal flows and Rossby waves

S Subbotin, N Shmakova, V Kozlov, E Ermanyuk - Physics of Fluids, 2023 - pubs.aip.org
Fluid flow excited by inertial waves in a rotating annulus with a trapezoidal cross section is
experimentally investigated. The forcing is introduced by the precession of a flat annular lid …

Interplay between geostrophic vortices and inertial waves in precession-driven turbulence

F Pizzi, G Mamatsashvili, AJ Barker, A Giesecke… - Physics of …, 2022 - pubs.aip.org
The properties of rotating turbulence driven by precession are studied using direct numerical
simulations and analysis of the underlying dynamical processes in Fourier space. The study …

Precession-driven flows in stress-free ellipsoids

J Vidal, D Cébron - Journal of Fluid Mechanics, 2023 - cambridge.org
Motivated by modelling rotating turbulence in planetary fluid layers, we investigate
precession-driven flows in ellipsoids subject to stress-free boundary conditions (SF-BC). The …

Prograde and retrograde precession of a fluid-filled cylinder

F Pizzi, A Giesecke, J Šimkanin… - New Journal of …, 2021 - iopscience.iop.org
We numerically study precession driven flows in a cylindrical container whose nutation
angle varies between 60 and 90 degrees for prograde and retrograde precession. For …
