Quantifying resonant and near-resonant interactions in rotating turbulence
(Cambridge University Press, 2016-11)
Nonlinear triadic interactions are at the heart of our understanding of turbulence. In flows where waves are present, modes must not only be in a triad to interact, but their frequencies must also satisfy an extra condition: ...
Isotropization at small scales of rotating helically driven turbulence
(Cambridge University Press, 2012-04)
We present numerical evidence of how three-dimensionalization occurs at small scale in rotating turbulence with Beltrami (ABC) forcing, creating helical flow. The Zeman scale ℓ Ω at which the inertial and eddy turn-over ...
SYNCHRONIZATION OF CHAOS AND THE TRANSITION TO WAVE TURBULENCE
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We investigated the transition to wave turbulence in a spatially extended three-wave interacting model, where a spatially homogeneous state undergoing chaotic dynamics undergoes spatial mode excitation. The transition to ...
Flow-sediment turbulent ejections: interaction between surface and subsurface flow in gravel-bed contaminated by fine sediment
(MDPI, 2020)
Several researchers have studied turbulent structures, such as ejections, sweeps, and outwards and inwards interactions in flumes, where the streamwise velocity dominates over vertical and transversal velocities. However, ...
Review of wave-turbulence interactions in the stable atmospheric boundary layer
(American Geophysical Union, 2015-09)
Flow in a stably stratified environment is characterized by anisotropic and intermittent turbulence and wavelike motions of varying amplitudes and periods. Understanding turbulence intermittency and wave-turbulence ...
Low-dimensional chaos and wave turbulence in plasmas
(ROYAL SOC, 2008)
We investigated drift-wave turbulence in the plasma edge of a small tokamak by considering solutions of the Hasegawa-Mima equation involving three interacting modes in Fourier space. The resulting low-dimensional dynamics ...
Scale interactions in magnetohydrodynamic turbulence
(Annual Reviews, 2011-01)
This article reviews recent studies of scale interactions in magnetohydrodynamic turbulence. The present-day increase of computing power, which allows for the exploration of different configurations of turbulence in ...
Helicity cascades in rotating turbulence
(American Physical Society, 2009-12)
The effect of helicity (velocity-vorticity correlations) is studied in direct numerical simulations of rotating turbulence down to Rossby numbers of 0.02. The results suggest that the presence of net helicity plays an ...
On the interactión of ocean waves and turbulence
(2010)
The interaction of ocean waves and turbulence is a fundamental process in the ocean. Understanding and prediction of wind-wave generation, propagation, breaking, non-linear interactions and extreme wave development are ...
