Turbulence theories and statistical closure approaches

Y Zhou - Physics Reports, 2021 - Elsevier
When discussing research in physics and in science more generally, it is common to ascribe
equal importance to the three components of the scientific trinity: theoretical, experimental …

Southern O cean eddy phenomenology

I Frenger, M Münnich, N Gruber… - Journal of Geophysical …, 2015 - Wiley Online Library
Mesoscale eddies are ubiquitous features in the Southern Ocean, yet their phenomenology
is not well quantified. To tackle this task, we use satellite observations of sea level …

Upscale energy transfer in thick turbulent fluid layers

H Xia, D Byrne, G Falkovich, M Shats - Nature Physics, 2011 - nature.com
Flows in natural fluid layers are often forced simultaneously at scales smaller and much
larger than the depth. For example, the Earth's atmospheric flows are powered by gradients …

Spectrally condensed turbulence in thin layers

H Xia, M Shats, G Falkovich - Physics of Fluids, 2009 - pubs.aip.org
We present experimental results on the properties of bounded turbulence in thin fluid layers.
In contrast with the theory of two-dimensional (2D) turbulence, the effects of the bottom …

Quiet periods in edge turbulence preceding the LH transition in the National Spherical Torus Experiment

Fixed-flux Rayleigh–Bénard convection in doubly periodic domains: generation of large-scale shear

C Liu, M Sharma, K Julien, E Knobloch - Journal of Fluid Mechanics, 2024 - cambridge.org
This work studies two-dimensional fixed-flux Rayleigh–Bénard convection with periodic
boundary conditions in both horizontal and vertical directions and analyses its dynamics …

Turbulence-condensate interaction in two dimensions

H Xia, H Punzmann, G Falkovich, MG Shats - Physical review letters, 2008 - APS
We present experimental results on turbulence generated in thin fluid layers in the presence
of a large-scale coherent flow, or a spectral condensate. It is shown that the condensate …

Interaction between mean flow and turbulence in two dimensions

G Falkovich - Proceedings of the Royal Society A …, 2016 - royalsocietypublishing.org
This short note is written to call attention to an analytic approach to the interaction of
developed turbulence with mean flows of simple geometry (jets and vortices). It is instructive …

Condensates in thin-layer turbulence

A van Kan, A Alexakis - Journal of Fluid Mechanics, 2019 - cambridge.org
We examine the steady state of turbulent flows in thin layers using direct numerical
simulations. It is shown that when the layer thickness is smaller than a critical height, an …
