Role of the forcing dimensionality in thin-layer turbulent energy cascades
Basile Poujol, Adrian van Kan, Alexandros Alexakis
We investigate the transition from forward to inverse energy cascade in turbulent flows in thin layers, varying the functional form of the forcing and the thickness of the layer. W…

Critical transition in fast-rotating turbulence within highly elongated domains
Adrian van Kan, Alexandros Alexakis
We study rapidly rotating turbulent flows in a highly elongated domain using an asymptotic expansion at simultaneously low Rossby number and large domain height compared…

Rare transitions to thin-layer turbulent condensates
Adrian van Kan, Takahiro Nemoto, Alexandros Alexakis
Turbulent flows in a thin layer can develop an inverse energy cascade leading to spectral condensation of energy when the layer height is smaller than a certain threshold. These sp…
