Epistemic and Aleatoric Uncertainty Quantification and Surrogate Modelling in High-Performance Multiscale Plasma Physics Simulations
Yehor Yudin, David Coster, Udo von Toussaint +1
This work suggests several methods of uncertainty treatment in multiscale modelling and describes their application to a system of coupled turbulent transport simulations of a toka…
Validation of edge turbulence codes against the TCV-X21 diverted L-mode reference case
D. S. Oliveira, T. Body, D. Galassi +27
Self-consistent full-size turbulent-transport simulations of the divertor and SOL of existing tokamaks have recently become feasible. This enables the direct comparison of turbulen…
Equations and improved coefficients for paralleltransport in multicomponent collisional plasmas: method and application for tokamak modelling
S. Makarov, D. Coster, V. Rozhansky +5
New analytical expressions for parallel transport coefficients in multicomponent collisional plasmas are presented in this paper. They are improved versions of the expressions writ…
Collisional gyrokinetic full-f particle-in-cell simulations on open field lines with PICLS
Mathias Boesl, Andreas Bergmann, Alberto Bottino +3
Applying gyrokinetic simulations for theoretical turbulence and transport studies to the plasma edge and scrape-off layer (SOL) presents significant challenges. To in particular ac…
Treatment of Advanced Divertor Configurations in the Flux-Coordinate Independent turbulence code GRILLIX
Thomas Body, Andreas Stegmeir, Wladimir Zholobenko +2
Advanced divertor configurations modify the magnetic geometry of the diverter to achieve a combination of strong magnetic flux expansion, increased connection length and higher div…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
Gyrokinetic full-f particle-in-cell simulations on open field lines with PICLS
Mathias Helmut Boesl, Andreas Bergmann, Alberto Bottino +4
While in recent years, gyrokinetic simulations have become the workhorse for theoretical turbulence and transport studies in the plasma core, their application to the edge and scra…
Global turbulence simulations of the tokamak edge region with GRILLIX
A. Stegmeir, A. Ross, T. Body +8
Turbulent dynamics in the scrape-off layer (SOL) of magnetic fusion devices is intermittent with large fluctuations in density and pressure. Therefore, a model is required that all…
The field line map approach for simulations of magnetically confined plasmas
Andreas Stegmeir, David Coster, Omar Maj +2
In the presented field line map approach the simulation domain of a tokamak is covered with a cylindrical grid, which is Cartesian within poloidal planes. Standard finite-differenc…
