Cascades and transitions in turbulent flows
A Alexakis, L Biferale - Physics Reports, 2018 - Elsevier
Turbulent flows are 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 …

Radiative heating achieves the ultimate regime of thermal convection
The absorption of light or radiation drives turbulent convection inside stars, supernovae,
frozen lakes, and Earth's mantle. In these contexts, the goal of laboratory and numerical …

Direct and inverse energy cascades in a forced rotating turbulence experiment
We present experimental evidence for a double cascade of kinetic energy in a statistically
stationary rotating turbulence experiment. Turbulence is generated by a set of vertical flaps …

Two-dimensional turbulence above topography: condensation transition and selection of minimum enstrophy solutions
B Gallet - Journal of Fluid Mechanics, 2024 - cambridge.org
We consider two-dimensional flows above topography, revisiting the selective decay (or
