An alternative approach to Direct Numerical Simulations (DNS) of Magnetohydrodynamics (MHD) is presented, providing insight into the statistical properties of highly-turbulent, intermittent, anisotropic MHD turbulence: a set of shell-models coupled by Alfvén waves travelling along the axial magnetic field and which interact non-linearly, producing perpendicular fluctuations of the fields at small scales. This model can be applied to different physical situations; we present the cases of heating in solar coronal loops, and of turbulence in open coronal regions at the base of the solar wind.

Abstract

An alternative approach to Direct Numerical Simulations (DNS) of Magnetohydrodynamics (MHD) is presented, providing insight into the statistical properties of highly-turbulent, intermittent, anisotropic MHD turbulence: a set of shell-models coupled by Alfvén waves travelling along the axial magnetic field and which interact non-linearly, producing perpendicular fluctuations of the fields at small scales. This model can be applied to different physical situations; we present the cases of heating in solar coronal loops, and of turbulence in open coronal regions at the base of the solar wind.
