Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

We study the bifurcations of the large-scale jets in the turbulent regime of a forced shear flow
using direct numerical simulations of the Navier-Stokes equations. The bifurcations are seen …

This paper examines the behavior of the dimensionless dissipation rate C ɛ for stationary
and nonstationary magnetohydrodynamic (MHD) turbulence in the presence of external …

We present an efficient dimension-by-dimension finite-volume method which solves the
adiabatic magnetohydrodynamics equations at high discretization order, using the …

A Hamiltonian two-field gyrofluid model for kinetic Alfvén waves (KAWs) in a magnetized
electron–proton plasma, retaining ion finite-Larmor-radius corrections and parallel magnetic …

We study the statistically steady states of the forced dissipative three-dimensional
homogeneous isotropic turbulence at scales larger than the forcing scale in real separation …

Using direct numerical simulations, we demonstrate that magnetic helicity exhibits a
bidirectional turbulent cascade at high but finite magnetic Reynolds numbers. Despite the …

We investigate the impact of a solid-body rotation Ω 0 on the large-scale dynamics of an
incompressible magnetohydrodynamic turbulent flow in presence of a background magnetic …

For the quadratic helicity χ (2), we present a generalization of the Arnol'd inequality which
relates the magnetic energy to the quadratic helicity, which poses a lower bound. We then …

The inverse transfer of magnetic helicity is a fundamental process that may explain large-
scale magnetic structure formation and sustainment. Until very recently, direct numerical …
