Global full-f gyrokinetic simulations of plasma turbulence
Critical physical issues can be specifically tackled with the global full-f gyrokinetic code GYSELA. Three main results are presented. First, the selfconsistent treatment of equilibrium and fluctuations highlights the competition between two compensation mechanisms for the curvature driven vertical charge separation, namely, parallel flow and polarization. The impact of the latter on the turbul...
متن کاملParticle pinch in gyrokinetic simulations of closed field-line systems.
Gyrokinetic simulations of small-scale turbulent transport in a closed magnetic field-line plasma geometry are presented. The simulations are potentially applicable to dipolar systems such as the levitated dipole experiment (LDX) [J. Kesner, Plasma Phys. Rep. 23, 742 (1997).] and planetary magnetospheres, as well as simpler systems such as the Z pinch. We report here for the first time the exis...
متن کاملGlobal gyrokinetic particle simulations with kinetic electrons
A toroidal, nonlinear, electrostatic fluid-kinetic hybrid electron model is formulated for global gyrokinetic particle simulations of driftwave turbulence in fusion plasmas. Numerical properties are improved by an expansion of the electron response using a smallness parameter of the ratio of driftwave frequency to electron transit frequency. Linear simulations accurately recover the real freque...

متن کاملFull-f gyrokinetic simulations on rotation changes induced by electron heating modulation
Reversal or change of intrinsic rotation is one of outstanding issues in recent momentum transport experiments. Although several theoretical models were proposed, its mechanism is still uncertain. We address this issue based on numerical experiments using a Gyrokinetic Toroidal 5D full-f Eulerian code GT5D [1], in which detailed mechanisms of momentum transport and the resulting intrinsic rotat...
