  • Anisotropic three-dimensional MHD turbulence

    Matthaeus, William H.; Ghosh, Sanjoy; Oughton, Sean; Roberts, D. Aaron (1996)
    Direct spectral method simulation of the three-dimensional magnetohydrodynamics (MHD) equations is used to explore anisotropy that develops from initially isotropic fluctuations as a consequence of a uniform applied magnetic ...
  • Conditions for sustainment of magnetohydrodynamic turbulence driven by Alfvén waves

    Dmitruk, Pablo; Matthaeus, William H.; Milano, L. J.; Oughton, Sean (American Institute of Physics, 2001)
    In a number of space and astrophysical plasmas,turbulence is driven by the supply of wave energy. In the context of incompressible magnetohydrodynamics (MHD) there are basic physical reasons, associated with conservation ...
  • Coronal heating by magnetohydrodynamic turbulence driven by reflected low-frequency waves

    Matthaeus, William H.; Zank, Gary P.; Oughton, Sean; Mullan, D. J.; Dmitruk, Pablo (IOP PUBLISHING LTD, 1999)
    A candidate mechanism for the heating of the solar corona in open field line regions is described. The interaction of Alfvén waves, generated in the photosphere or chromosphere, with their reflections and the subsequent ...
  • Coronal heating distribution due to low-frequency, wave-driven turbulence

    Dmitruk, Pablo; Matthaeus, William H.; Milano, L. J.; Oughton, Sean; Zank, Gary P.; Mullan, D. J. (University of Chicago Press, 2002)
    The heating of the lower solar corona is examined using numerical simulations and theoretical models of magnetohydrodynamic turbulence in open magnetic regions. A turbulent energy cascade to small length scales perpendicular ...
  • Coronal MHD transport theory and phenomenology

    Milano, L. J.; Matthaeus, William H.; Dmitruk, Pablo; Oughton, Sean (American Institute of Physics, 2003)
    In the presence of a weakly inhomogeneous background, magnetohydrodynamic fluctuations are transported, reflected and at small scales, dissipated. In contrast to orderings appropriate to outer solar wind conditions, here ...
