The effect of helicity on the correlation time of large scale turbulent flows
Alexandre Cameron, Alexandros Alexakis, Marc-Étienne Brachet
Solutions of the forced Navier-Stokes equation have been conjectured to thermalize at scales larger than the forcing scale, similar to an absolute equilibrium obtained for the spec…
A systematic method to enforce conservativity on semi-Lagrangian schemes
Alexandre Cameron, Emmanuel Dormy
Semi-Lagrangian schemes have proven to be very efficient to model advection problems. However most semi-Lagrangian schemes are not conservative. Here, a systematic method is introd…
The fate of alpha dynamos at large
Alexandre Cameron, Alexandros Alexakis
At the heart of today's solar magnetic field evolution models lies the alpha dynamo description. In this work, we investigate the fate of alpha-dynamos as the magnetic Reynolds num…
Multi-stage high order semi-Lagrangian schemes for incompressible flows in Cartesian geometries
Alexandre Cameron, Raphaël Raynaud, Emmanuel Dormy
Efficient transport algorithms are essential to the numerical resolution of incompressible fluid flow problems. Semi-Lagrangian methods are widely used in grid based methods to ach…
Large-scale instabilities of helical flows
Alexandre Cameron, Alexandros Alexakis, Marc-Étienne Brachet
Large-scale hydrodynamic instabilities of periodic helical flows are investigated using D Floquet numerical computations. A minimal three-modes analytical model that reproduce a…
