Extraction of invariant manifolds and application to turbulence with a passive scalar
Nicolas E. Sujovolsky, Pablo D. Mininni
The reduction of dimensionality of physical systems, specially in fluid dynamics, leads in many situations to nonlinear ordinary differential equations which have global invariant…
From waves to convection and back again: The phase space of stably stratified turbulence
Nicolas E. Sujovolsky, Pablo D. Mininni
We show that the phase space of stratified turbulence mainly consists of two slow invariant manifolds with rich physics, embedded on a larger basin with fast evolution. A local inv…
Invariant manifolds in stratified turbulence
Nicolás E. Sujovolsky, Gabriel B. Mindlin, Pablo D. Mininni
We present a reduced system of 7 ordinary differential equations that captures the time evolution of spatial gradients of the velocity and the temperature in fluid elements of stra…
Statistics of single and multiple floaters in experiments of surface wave turbulence
Nicolás F. Del Grosso, Lucía M. Cappelletti, Nicolás E. Sujovolsky +2
We present laboratory experiments of surface wave turbulence excited by paddles in the deep water regime. The free surface is seeded with buoyant particles that are advected and di…
Vertical dispersion of Lagrangian tracers in fully developed stably stratified turbulence
Nicolas E. Sujovolsky, Pablo D. Mininni
We study the effect of different forcing functions and of the local gradient Richardson number Rig on the vertical mixing of Lagrangian tracers in stably stratified turbulence unde…
Generation of turbulence through frontogenesis in sheared stratified flows
N. E. Sujovolsky, P. D. Mininni, A. Pouquet
The large-scale structures in the ocean and the atmosphere are in geostrophic balance, and a conduit must be found to channel the energy to the small scales where it can be dissipa…
Single-particle dispersion in stably stratified turbulence
Nicolas E. Sujovolsky, Pablo D. Mininni, Mark P. Rast
We present models for single-particle dispersion in vertical and horizontal directions of stably stratified flows. The model in the vertical direction is based on the observed Lagr…
Tridimensional to bidimensional transition in magnetohydrodynamic turbulence with a guide field and kinetic helicity injection
N. E. Sujovolsky, P. D. Mininni
We study the transition in dimensionality of a three-dimensional magnetohydrodynamic flow forced only mechanically, when the strength of a magnetic guiding field is gradually incre…
