The Lagrangian-averaged model for magnetohydrodynamics turbulence and the absence of bottleneck
Jonathan Pietarila Graham, Pablo D. Mininni, Annick Pouquet
We demonstrate that, for the case of quasi-equipartition between the velocity and the magnetic field, the Lagrangian-averaged magnetohydrodynamics alpha-model (LAMHD) reproduces we…
Energy transfer in Hall-MHD turbulence: cascades, backscatter, and dynamo action
P. D. Mininni, A. Alexakis, A. Pouquet
Scale interactions in Hall MHD are studied using both the mean field theory derivation of transport coefficients, and direct numerical simulations in three space dimensions. In the…
On the inverse cascade of magnetic helicity
Alexandros Alexakis, Pablo Mininni, Annick Pouquet
We study the inverse cascade of magnetic helicity in conducting fluids by investigating the detailed transfer of helicity between different spherical shells in Fourier space in dir…
Cancellation exponent and multifractal structure in two-dimensional magnetohydrodynamics: direct numerical simulations and Lagrangian averaged modeling
Jonathan Pietarila-Graham, Pablo D. Mininni, Annick Pouquet
We present direct numerical simulations and Lagrangian averaged (also known as alpha-model) simulations of forced and free decaying magnetohydrodynamic turbulence in two dimensions…
