On local and non-local energy transfers in Hall magnetohydrodynamic turbulence
Arijit Halder, Supratik Banerjee, Pablo D. Mininni +1
A systematic study of inertial energy cascade in three-dimensional incompressible Hall magnetohydrodynamic turbulence is conducted to probe into the locality of energy conserving t…
An in-depth numerical study of exact laws for compressible Hall magnetohydrodynamic turbulence
R. Ferrand, F. Sahraoui, S. Galtier +3
Various exact laws governing compressible magnetohydrodynamic (MHD) and Hall-MHD (CHMHD) turbulence have been derived in recent years. Other than their fundamental theoretical inte…
Energy cascade rate in isothermal compressible magnetohydrodynamic turbulence
Nahuel Andrés, Fouad Sahraoui, Sébastien Galtier +3
Three-dimensional direct numerical simulations are used to study the energy cascade rate in isothermal compressible magnetohydrodynamic turbulence. Our analysis is guided by a two-…
Interplay between Alfvén and magnetosonic waves in compressible magnetohydrodynamics turbulence
Nahuel Andrés, Patricio Clark di Leoni, Pablo D. Mininni +3
Using spatio-temporal spectra we show direct evidence of excitation of magnetosonic and Alfvén waves in three-dimensional compressible magnetohydrodynamic turbulence at small Mach…
On the spatio-temporal behavior of magnetohydrodynamic turbulence in a magnetized plasma
R. Lugones, P. Dmitruk, P. D. Mininni +2
Using direct numerical simulations of three-dimensional magnetohydrodynamic (MHD) turbulence the spatio-temporal behavior of magnetic field fluctuations is analyzed. Cases with rel…
von Kármán-Howarth equation for three-dimensional two-fluid plasmas
Nahuel Andrés, Pablo Mininni, Pablo Dmitruk +1
We derive the von Kármán-Howarth equation for a full three dimensional incompressible two-fluid plasma. In the long-time limit and for very large Reynolds numbers we obtain the equ…
Ideal evolution of MHD turbulence when imposing Taylor-Green symmetries
M. E. Brachet, M. D. Bustamante, G. Krstulovic +3
We investigate the ideal and incompressible magnetohydrodynamic (MHD) equations in three space dimensions for the development of potentially singular structures. The methodology co…
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…
