Equilibrium states of two|dimensional turbulence

Transitions to condensate formation in two-dimensional turbulence ...

A characteristic feature of turbulence in 2d and thin fluid layers is the occurrence of an inverse energy cascade. In case of weak Rayleigh damping the inverse ...

Symmetry breaking in two-dimensional turbulence induced by out-of ...

The study demonstrates that out-of-equilibrium fluxes, specifically the direct cascade of energy to small scales, can fundamentally shape the self-organization ...

Robustness of the inverse cascade in two-dimensional turbulence

Turbulence in a bounded do- main will eventually approach an equilibrium state [12], with ǫ0 = dE/dt = 0. We thus recover a principal result from Refs. 7 ...

A new formulation of the near-equilibrium theory of turbulence 1

The heuristic explanation of this phenomenon is that in the presence of two constraints there are ever fewer states that satisfy both constraints; the effective ...

UMR 5152 - Two-dimensional turbulence and stellar systems

Two-dimensional flows with high Reynolds numbers have the striking property of organizing spontaneously into large scale coherent vortices.

Recurrent flow patterns as a basis for two-dimensional turbulence

A dynamical systems approach to turbulence envisions the flow as a trajectory through a high-dimensional state space [Hopf, Commun. Appl. Maths 1, 303 (1948)].

On the late phase of relaxation of two-dimensional fluids: turbulence ...

In this work we examine the advanced phases of relaxation of the two-dimensional ideal (Euler) fluid. This state consists of few robust vortices interacting ...

On final states of two-dimensional decaying turbulence - Pure

The flow is not described by any functional relation be- tween ␻ and ␺, but it manages to go to one specific kind of equilibrium state. It is ...

Modeling mixing in two-dimensional turbulence and stratified fluids

ii) We propose relaxation equations toward the equilibrium states for stratified flows, based on a work devel- oped previously in the context of 2D flows. Two ...

Detecting Non-stationary and Non-equilibrium States in Atmospheric ...

In the coupled cloud, the turbulence seems to undergo a series of equilibrium states. In the decoupled one, non-equilibrium states were detected. The presence ...
