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…
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 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…
Simulating X-point radiator turbulence
K. Eder, W. Zholobenko, A. Stegmeir +5
Coupling a high-performance burning plasma core to a detached boundary solution is critical for realizing magnetic confinement fusion power. Predictive simulations of the edge and…
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…
Tokamak edge-SOL turbulence in H-mode conditions simulated with a global, electromagnetic, transcollisional drift-fluid model
Wladimir Zholobenko, Kaiyu Zhang, Andreas Stegmeir +8
The design of commercially feasible magnetic confinement fusion reactors strongly relies on the reduced turbulent transport in the plasma edge during operation in the high confinem…
Magnetic flutter effect on validated edge turbulence simulations
Kaiyu Zhang, Wladimir Zholobenko, Andreas Stegmeir +2
Small magnetic fluctuations () are intrinsically present in a magnetic confinement plasma due to turbulent currents. While the perpendicular transport of part…
preCICE v2: A Sustainable and User-Friendly Coupling Library
Gerasimos Chourdakis, Kyle Davis, Benjamin Rodenberg +17
preCICE is a free/open-source coupling library. It enables creating partitioned multi-physics simulations by gluing together separate software packages. This paper summarizes the d…
