On the thermal equilibrium state of large scale flows
Alexandros Alexakis, Marc-Etienne Brachet
In a forced three-dimensional turbulent flow the scales larger than the forcing scale have been conjectured to reach a thermal equilibrium state forming a energy spectrum. In…
Cascades and transitions in turbulent flows
A. Alexakis, L. Biferale
Turbulence is characterized by the non-linear cascades of energy and other inviscid invariants across a huge range of scales, from where they are injected to where they are dissipa…
Condensates in thin-layer turbulence
Adrian van Kan, Alexandros Alexakis
We examine the steady state of turbulent flows in thin layers using direct numerical simulations. It is shown that when the layer thickness is smaller than a critical height, an in…
3D instabilities and negative eddy viscosity in thin-layer flows
Alexandros Alexakis
The stability of flows in layers of finite thickness is examined against small scale three dimensional (3D) perturbations and large scale two-dimensional (2D) perturbations. Th…
