Turbulent Nature of the Quasicontinuous Exhaust Regime for Fusion Plasmas
Kaiyu Zhang, Wladimir Zholobenko, Andreas Stegmeir +5
We demonstrate a turbulence mechanism that reconciles high plasma confinement with efficient heat exhaust -- a central challenge for fusion energy. Global two-fluid turbulence simu…
On the mechanism of Pedestal Relaxation Events -- Insights gained by turbulence simulations with GRILLIX
Christoph Pitzal, Andreas Stegmeir, Tim Happel +7
Pedestal Relaxation Events (PREs) appear in I-mode discharges close to the I-H transition. Although they show certain similarities with Edge Localised Modes (ELMs), i.e. periodic e…
The impact of plasma turbulence on atomic reaction rates in the detached ASDEX Upgrade divertor
Konrad Eder, Wladimir Zholobenko, Andreas Stegmeir +2
Numerical modeling of the edge and scrape-off layer (SOL) must account for atomic processes such as hydrogenic ionization and recombination, charge-exchange, and line radiation. Th…
On the proper treatment of magnetic fluctuations in full- field-aligned turbulence codes
Kaiyu Zhang, Wladimir Zholobenko, Andreas Stegmeir +2
Plasma turbulence in the edge of magnetic confinement devices is customarily treated as full- due to large fluctuations. For computational efficiency, field-aligned coordinates…
