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 ...
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: ...
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 ...
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 ...
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 ...
Absorption of waves by large-scale winds in stratified turbulence
(American Physical Society, 2015-03)
The atmosphere is a nonlinear stratified fluid in which internal gravity waves are present. These waves interact with the flow, resulting in wave turbulence that displays important differences with the turbulence observed ...
Coexistence of acoustic waves and turbulence in low Mach number compressible flows
(American Institute of Physics, 2019-04-04)
In this work, direct numerical simulations of the compressible fluid equations in turbulent regimes are performed. The behavior of the flow is either dominated by purely turbulent phenomena or by the generation of sound ...
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 ...
Blowout bifurcation and spatial mode excitation in the bubbling transition to turbulence
(ELSEVIER SCIENCE BV, 2011)
The transition to turbulence (spatio-temporal chaos) in a wide class of spatially extended dynamical system is due to the loss of transversal stability of a chaotic attractor lying on a homogeneous manifold (in the Fourier ...
