Journal ArticleDOI

Recovery of the Navier-Stokes equations using a lattice-gas Boltzmann method.

TL;DR: This paper shows that both of these effects of a non-Galilean invariance caused by a density-dependent coefficient in the convection term can be eliminated exactly in a lattice Boltzmann-equation model.
Journal ArticleDOI

Measurement of the rugged invariants of magnetohydrodynamic turbulence in the solar wind

TL;DR: In this paper, the authors measured the total energy, cross helicity, and magnetic helicity of the solar wind at 1, 2.8, and 5 AU, and found that the magnetic heliometry typically lies at scales larger than the magnetic correlation length, consistent with the expectations of the inverse cascade and selective decay hypotheses of three-dimensional MHD turbulence theory.
Journal ArticleDOI

Anisotropy in MHD turbulence due to a mean magnetic field

TL;DR: In this paper, the development of anisotropy in an initially isotropic spectrum is studied numerically for two-dimensional magnetohydrodynamic turbulence, due to the combined effects of an externally imposed dc magnetic field and viscous and resistive dissipation at high wave numbers.
Journal ArticleDOI

Observational constraints on the dynamics of the interplanetary magnetic field dissipation range

TL;DR: In this paper, the authors examined wind observations of inertial and dissipation range spectra in an attempt to better understand the processes that form the dissipation ranges and how these processes depend on the ambient solar wind parameters (interplanetary magnetic field intensity, ambient proton density and temperature, etc.).
Journal ArticleDOI

Evidence for the presence of quasi‐two‐dimensional nearly incompressible fluctuations in the solar wind

TL;DR: In this article, the authors proposed a model of the solar wind as a fluid which contains both classical transverse Alfvenic fluctuations and a population of quasi-transverse fluctuations.
