Journal ArticleDOI
Selective decay and coherent vortices in two-dimensional incompressible turbulence.
TL;DR: Numerical solution of two-dimensional incompressible hydrodynamics shows that states of a near-minimal ratio of enstrophy to energy can be attained in times short compared with the flow decay time, confirming the simplest turbulent selective decay conjecture, and suggesting that coherent vortex structures do not terminate nonlinear processes.
Journal ArticleDOI
Kinetic signatures and intermittent turbulence in the solar wind plasma.
TL;DR: A connection between kinetic processes and intermittent turbulence is observed in the solar wind plasma using measurements from the Wind spacecraft, and linear Vlasov theory is not sufficient to explain the inhomogeneous plasma dynamics operating near non-Gaussian structures.
Journal ArticleDOI
Transport of solar wind fluctuations: A two-component model
TL;DR: In this article, the authors presented a new model for the transport of solar wind fluctuations which treated them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.
Journal ArticleDOI
Particle-acceleration by turbulent magnetohydrodynamic reconnection
TL;DR: In this paper, a two dimensional, turbulent MHD simulation is found to undergo significant acceleration and the test particles are trapped in the reconnection region for times of order an Alfven transit time in the large electric fields that characterize the turbulent reconnection process at the relatively large magnetic Reynolds number used in the simulation.
Journal ArticleDOI
Anisotropy in solar wind plasma turbulence.
TL;DR: Evidence for and against wave interpretations and turbulence interpretations of these features will be discussed, and new simulation results concerning evolution of variance anisotropy for different classes of initial conditions, each with typical background solar wind parameters are presented.
