Eulerian-Lagrangian scaling of the Lyapunov exponent in homogeneous turbulence
Jin Ge, Joran Rolland, John Christos Vassilicos
We present a heuristic derivation of the maximal Lyapunov exponent of homogeneous turbulence which yields two new relations, a sweeping relation and the scaling of the uncertai…
Sea ice aging by diffusion-driven desalination
Yihong Du, Feng Wang, Enrico Calzavarini +1
Sea ice is a key component of the Earth's climate system, making its aging process an essential focus of current research. The age of sea ice is closely linked to its thermal and m…
Experimental measurement of the vorticity-strain alignment around extreme energy transfer events
Benjamin Musci, Berengere Dubrulle, Jean LeBris +5
This work experimentally explores the alignment of the vorticity vector and the strain-rate tensor eigenvectors at locations of extreme upscale and downscale energy transfer. We sh…
Active grid turbulence anomalies through the lens of physics informed neural networks
Sofía Angriman, Sarah E. Smith, Patricio Clark di Leoni +3
Active grids operated with random protocols are a standard way to generate large Reynolds number turbulence in wind and water tunnels. But anomalies in the decay and third-order sc…
Impact of ageostrophic dynamics on the predictability of Lagrangian trajectories in surface-ocean turbulence
Michael Maalouly, Guillaume Lapeyre, Stefano Berti
Turbulent flows at the surface of the ocean deviate from geostrophic equilibrium on scales smaller than about 10 km. These scales are associated with important vertical transport o…
Does rare, noise-induced, bypass transition in plane Couette flow bypass instantons ?
Joran Rolland
We study rare noise induced paths that go all the way from stable laminar to transitional turbulent plane Couette flow and investigate whether these paths share the properties of c…
