Conservation laws, fluxes, and symmetries: lessons from a perturbative approach for self-organized turbulence
Anna Frishman, Sébastien Gomé, Anton Svirsky
Some turbulent flows self-organize into large-scale structures, rather than breaking up into ever-smaller scales. Underpinning this phenomenon is the existence of two sign-definite…

Self-Replication of Turbulent Puffs: On the edge between chaotic saddles
Anton Svirsky, Tobias Grafke, Anna Frishman
Pipe flow is a canonical example where turbulence first appears intermittently in space and time, taking the form of localized structures termed puffs. Turbulence spreads via puff…

Out-of-equilibrium fluxes shape the self-organization of locally-interacting turbulence
Anton Svirsky, Anna Frishman
We study the self-organization of turbulence in a geophysically motivated two-dimensional fluid with local interactions. Using simulations and theory, we show that the out-of-equil…
