Generation of weakly nonlinear turbulence of internal gravity waves in the Coriolis facility

C Savaro, A Campagne, MC Linares, P Augier… - Physical Review …, 2020 - APS
We investigate experimentally stratified turbulence forced by waves. Stratified turbulence is
present in oceans and it is expected to be dominated by nonlinear interaction of internal …

Direct numerical simulation of three-dimensional inertial wave attractors

I Sibgatullin, E Ermanyuk, L Maas, X Xu… - 2017 Ivannikov …, 2017 - ieeexplore.ieee.org
Internal (inertial) waves in a uniformly stratified (rotating) fluid obey a highly specific
dispersion relation that admits their propagation in form of oblique beams, which preserve …

Experimental quantification of nonlinear time scales in inertial wave rotating turbulence

E Yarom, A Salhov, E Sharon - Physical Review Fluids, 2017 - APS
We study nonlinearities of inertial waves in rotating turbulence. At small Rossby numbers the
kinetic energy in the system is contained in helical inertial waves with time dependence …

Separation of eddy turbulence and wave turbulence in rotating or stratified flows

H Lam - 2021 - theses.hal.science
Internal Gravity Waves (IGW) exist in stratified flows, where the density varies with height in a
stable stratification (heavy fluid below light fluid). This type of flow is encountered in the …

Аннотация Внутренние и инерционные волны подчиняются особому дисперсионному
соотношению, определяющему направление распространения волн по отношению к …

[PDF][PDF] INSTABILITIES AND ATTRACTORS IN LARGE ASPECT RATIO STRATI-FIED/ROTATING FLUIDS

I Sibgatullin, S Elistratov, X Xu - Proceedings Topical Problems of Fluid …, 2023 - it.cas.cz
Internal and inertial waves are ubiquitous in the world's oceans, and the energy that they
transfer from the global tide to the smaller scales may impact the vertical mixing and global …

OpenFOAM Solver Based on Regularized Hydrodynamic Equations for High Performance Computing

MV Shatskiy, DA Ryazanov, KA Vatutin… - 2019 Ivannikov …, 2019 - ieeexplore.ieee.org
In the paper we investigate scaling of parallel performance for an implementation of quasi-
hydrodynamic (QHD) approach as an OpenFOAM solver. Time-dependent partial differential …

[PDF][PDF] INTERNAL WAVE TURBULENCE IN LARGE ASPECT RATIO DOMAINS

I Sibgatullin, S Elistratov - it.cas.cz
Continuous stratification profoundly impacts the onset of hydrodynamical instabilities due to
a unique dispersion relation. According to this relation, wave beams and wave energy …
