Anomalous diffusion, clustering, and pinch of impurities in plasma edge turbulence
M. Priego, O. E. Garcia, V. Naulin +1
The turbulent transport of impurity particles in plasma edge turbulence is investigated. The impurities are modeled as a passive fluid advected by the electric and polarization dri…
Shear Flow Generation and Energetics in Electromagnetic Turbulence
V. Naulin, A. Kendl, O. E. Garcia +2
Zonal flows are recognised to play a crucial role for magnetised plasma confinement. The genesis of these flows out of turbulent fluctuations is therefore of significant interest.…
Intermittent transport in edge plasmas
Odd Erik Garcia, Volker Naulin, Anders Henry Nielsen +1
The properties of low-frequency convective fluctuations and transport are investigated for the boundary region of magnetized plasmas. We employ a two-dimensional fluid model for th…
Numerical Simulations of Intermittent Transport in Scrape-Off Layer Plasmas
Odd Erik Garcia, Volker Naulin, Anders H. Nielsen +1
Two-dimensional fluid simulations of interchange turbulence for geometry and parameters relevant for the scrape-off layer of confined plasmas are presented. We observe bursty eject…
Statistical properties of transport in plasma turbulence
Volker Naulin, Odd Erik Garcia, Anders Henry Nielsen +1
The statistical properties of the flux in different types of plasma turbulence simulations are investigated using probability density distribution functions (PDF). The…
