A penalized model for plasma-wall interaction valid in the gyrokinetic framework
Résumé
Context: gyrokinetic edge modelling requires plasma-wall interaction
▪ turbulent transport degrades tokamak confinement quality [Wootton 1990]
▪ Turbulence regulation mechanism: ExB sheared flows [Diamond 2005]
▪ Transport barriers formation at the separatrix is related to sheared flows [Wagner 1982]
▪ Global gyrokinetic codes need plasma-wall interaction to describe edge plasmas ➢ Plasma-wall interaction triggers turbulence in edge plasma [Dif-Pradalier 2022]
