The Problem of Marginality in Model Reductions of Turbulence
C. Gillot, G. Dif-Pradalier, Y. Sarazin +8
Reduced quasilinear (QL) and nonlinear (gradient-driven) models with scale separations, commonly used to interpret experiments and to forecast turbulent transport levels in magneti…
Transport barrier onset and edge turbulence shortfall in fusion plasmas
Guilhem Dif-Pradalier, Philippe Ghendrih, Yanick Sarazin +7
Turbulent plasmas notably self-organize to higher energy states upon application of additional free energy sources or modification of edge operating conditions. Mechanisms whereby…
Analysis of fast turbulent reconnection with self-consistent determination of turbulence timescale
Fabien Widmer, Jörg Büchner, Nobumitsu Yokoi
We present results of Reynolds-averaged turbulence model simulation on the problem of magnetic reconnection. In the model, in addition to the mean density, momentum, magnetic field…
Electron acceleration by turbulent plasmoid reconnection
X. Zhou, J. Buechner, F. Widmer +1
In space and astrophysical plasmas, like in planetary magnetospheres, as that of Mercury,energetic electrons are often found near current sheets (CSs), which hints at electron acce…
Turbulent Plasmoid Reconnection
Fabien Widmer, Jörg Büchner, Nobumitsu Yokoi
The plasmoid instability may lead to fast magnetic reconnection through long current sheets(CS). It is well known that large-Reynolds-number plasmas easily become turbulent. We add…
Sub-Grid-Scale Description of Turbulent Magnetic Reconnection in Magnetohydrodynamics
Fabien Widmer, Jörg Büchner, Nobumitsu Yokoi
Magnetic reconnection requires, at least locally, a non-ideal plasma response. In collisionless space and astrophysical plasmas, turbulence could permit this instead of the too rar…
