Edge plasma relaxations due to diamagnetic stabilization
Francesco Cianfrani, Guillaume Fuhr, Peter Beyer
A new mechanism for pressure profile relaxations in an edge tokamak plasma is derived from simulations within the two-fluid three-dimensional turbulence code EMEDGE3D. The relaxati…
Flux driven pedestal formation in tokamaks: turbulence simulations validated against the isotope effect
G. De Dominici, G. Fuhr, P. Beyer +6
The spontaneous pedestal formation above a power threshold at the edge of magnetically confined plasma is modelled for the first time in flux driven three-dimensional fluid simulat…
L-H transition dynamics in fluid turbulence simulations with neoclassical force balance
Laurent Chôné, Peter Beyer, Yanick Sarazin +3
Spontaneous transport barrier generation at the edge of a magnetically confined plasma is investigated. To this end, a model of electrostatic turbulence in three-dimensional geomet…
Nonlinear Dynamics of Magnetic Islands Imbedded in Small-Scale Turbulence
Magali Muraglia, Oliver Agullo, Sadruddin Benkadda +3
The nonlinear dynamics of magnetic tearing islands imbedded in a pressure gradient driven turbulence is investigated numerically in a reduced magnetohydrodynamic model. The study r…
Effect of the curvature and the β parameter on the nonlinear dynamics of a drift tearing magnetic island
Magali Muraglia, Olivier Agullo, Masatoshi Yagi +6
We present numerical simulation studies of 2D reduced MHD equations investigating the impact of the electronic βparameter and of curvature effects on the nonlinear evolution of dri…
Shear flow effects on double tearing mode global magnetic reconnection
Thibaut Voslion, Olivier Agullo, Peter Beyer +5
The dynamics of a global reconnection in the presence of a poloidal shear flow which is located in between magnetic islands is investigated. Different linear regimes are identified…
