Spontaneous suppression of inverse energy cascade in instability-driven 2D turbulence
Adrian van Kan, Benjamin Favier, Keith Julien +1
Instabilities of fluid flows often generate turbulence. Using extensive direct numerical simulations, we study two-dimensional turbulence driven by a wavenumber-localised instabili…

Bistability of the large-scale dynamics in quasi-two-dimensional turbulence
Xander M. de Wit, Adrian van Kan, Alexandros Alexakis
In many geophysical and astrophysical flows, suppression of fluctuations along one direction of the flow drives a quasi-2D upscale flux of kinetic energy, leading to the formation…
