Electron and proton heating by solar wind turbulence [PDF]
, 2009 Previous formulations of heating and transport associated with strong magnetohydrodynamic (MHD) turbulence are generalized to incorporate separate internal energy equations for electrons and protons. Electron heat conduction is included.

On energetics and inertial-range scaling laws of two-dimensional magnetohydrodynamic turbulence [PDF]
, 2012 L. Blackbourn was supported by an EPSRC post-graduate studentship.We study two-dimensional magnetohydrodynamic turbulence, with an emphasis on its energetics and inertial range scaling laws.

An analytical, phenomenological and numerical study of geophysical and magnetohydrodynamic turbulence in two dimensions [PDF]
, 2013 In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes (2DNS), surface quasigeostrophic

Turbulence development behind the bow shock during disturbed and undisturbed solar wind
Solar-Terrestrial PhysicsMagnetosheath is a transition layer between the solar wind and the magnetosphere and may contribute to the geoeffectiveness of various large-scale interplanetary phenomena.

Parallel and perpendicular cascades in solar wind turbulence [PDF]
, 2005 MHD-scale fluctuations in the velocity, magnetic, and density fields of the solar wind are routinely observed. The evolution of these fluctuations, as they are transported radially outwards by the solar wind, is believed to involve both wave and ...

Kinetic helicity and MHD turbulence [PDF]
, 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 various isotropic initial states ...

von Kármán self-preservation hypothesis for magnetohydrodynamic turbulence and its consequences for universality [PDF]
, 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 independent similarity length ...

Radial evolution of power spectra of interplanetary Alfvénic turbulence [PDF]
Journal of Geophysical Research: Space Physics, 1982 The radial evolution of the power spectra of the MHD turbulence within the trailing edge of high‐speed streams in the solar wind has been investigated with the magnetic field data of HELIOS 1 and 2 for heliocentric distances between 0.3 and 0.9 AU. In the analyzed frequency range 2.8 · 10−4 ‐ 8.3 · 10−2 Hz the computed spectra have, near the earth ...

The Astrophysical Journal, 2023 Large surveys of the power spectral density of the magnetic fluctuations in the solar wind have reported different slope distributions at MHD, sub-ion and sub-electron scales: the smaller the scale, the broader the distribution.
