  • Kinetic helicity and MHD turbulence

    Oughton, Sean; Prandi, Rossella (Cambridge University Press, 2000)
    The issue of dynamical anisotropy in helical three-dimensional magnetohydrodynamic turbulence with a mean magnetic field B₀ is investigated. Using high-resolution direct numerical simulations, we follow the evolution of ...

  • Radial evolution of cross helicity at low and high latitudes in the solar wind

    Breech, Ben; Matthaeus, William H.; Minnie, J.; Oughton, Sean; Parhi, S.; Bieber, J.W.; Bavassano, B. (2005)
    We employ a turbulence transport theory to the radial evolution of the solar wind at both low and high latitudes. The theory includes cross helicity, magnetohydrodynamic (MHD) turbulence, and driving by shear and pickup ...

  • A two-component phenomenology for the evolution of MHD turbulence

    Oughton, Sean; Dmitruk, Pablo; Matthaeus, William H. (Published on CD ROM, 2005)
    Incompressible MHD turbulence with a mean magnetic field B₀ develops anisotropic spectral structure and can be simply described only by including at least two distinct fluctuation components. These are conveniently referred ...

  • von Kármán self-preservation hypothesis for magnetohydrodynamic turbulence and its consequences for universality

    Wan, Minping; Oughton, Sean; Servidio, Sergio; Matthaeus, William H. (Cambridge University Press, 2012)
    We argue that the hypothesis of preservation of shape of dimensionless second- and third-order correlations during decay of incompressible homogeneous magnetohydrodynamic (MHD) turbulence requires, in general, at least two ...
