Internal gravity waves versus inertial waves in the laboratory

S Joubaud, S Boury, P Odier - Comptes …, 2024 - comptes-rendus.academie-sciences …
Density-stratified and/or rotating fluids are very common in geophysical and astrophysical
flows and enable the propagation of respectively internal gravity waves and inertial waves …

Succession of resonances to achieve internal wave turbulence

G Davis, T Jamin, J Deleuze, S Joubaud, T Dauxois - Physical Review Letters, 2020 - APS
We study experimentally the interaction of nonlinear internal waves in a stratified fluid
confined in a trapezoidal tank. The setup has been designed to produce internal wave …

laboratory a turbulence of internal gravity waves in a density stratified fluid in the weakly non …

Inertial wave super-attractor in a truncated elliptic cone

B Favier, S Le Dizès - Journal of Fluid Mechanics, 2024 - cambridge.org
We consider inertial waves propagating in a fluid contained in a non-axisymmetric three-
dimensional rotating cavity. We focus on the particular case of a fluid enclosed inside a …

Linear and nonlinear regimes of an inertial wave attractor

M Brunet, T Dauxois, PP Cortet - Physical Review Fluids, 2019 - APS
We present an experimental analysis of the linear and nonlinear regimes of an attractor of
inertial waves in a trapezoidal cavity under rotation. Varying the rotation rate and the forcing …

Forced internal wave attractors: linear inviscid theory

ZV Makridin, AK Khe, IN Sibgatullin, EV Ermanyuk - Physical Review Fluids, 2023 - APS
In this paper, we study internal wave focusing in a trapezoidal domain with one moving
boundary. Using linear theory, we construct an exact analytic solution for the case of ideal …

Near-field internal wave beams in two dimensions
