This lecture presents the gyrokinetic framework and details the various numerical schemes used in nonlinear simulations to compute turbulent transport in magnetic fusion plasmas. The basic features of tokamak magnetic configuration and of fusion …
Evidence for the impact of energetic particles (EPs) on turbulence is given in this paper. Firstly, the excitation of electrostatic instabilities in linear gyrokinetic simulations performed with the global GYSELA code by introducing distribution …
The creation of ion transport barriers by externally induced sheared E × B flows is investigated with the global, full-f and flux-driven gyrokinetic code GYSELA. A gyrokinetic source of vorticity is designed and proves to be efficient in polarizing …
Various indications on the weakly nonlocal character of turbulent plasma transport both from experimental fluctuation measurements from Tore Supra and observations from the full- f , flux-driven gyrokinetic code GYSELA are reported. A simple Fisher …
