Global electromagnetic gyrokinetic simulations of internal transport barriers in reversed-shear tokamaks
Giovanni Di Giannatale, Arnas Volčokas, Justin Ball +6
This work aims at improving our understanding of the conditions enabling the development of an Internal transport barriers (ITB), using a more comprehensive physical model, includi…
Gyrokinetic flux-driven simulations in mixed TEM/ITG regime using a delta-f PIC scheme with evolving background
Moahan Murugappan, Laurent Villard, Stephan Brunner +3
In the context of global gyrokinetic simulations of turbulence using a Particle-In-Cell framework, verifying the delta-f assumption with a fixed background distribution becomes cha…
System size scaling of triangularity effects on global temperature gradient-driven gyrokinetic simulations
Giovanni Di Giannatale, Alberto Bottino, Stephan Brunner +2
In this work, we explore the triangularity effects on turbulent transport employing global gyrokinetic simulations performed with the ORB5 code. Numerous experiments on the Tokamak…
Verification of the Fourier-enhanced 3D finite element Poisson solver of the gyrokinetic full-f code PICLS
Annika Stier, Alberto Bottino, Mathias Boesl +8
We introduce and derive the Fourier-enhanced 3D electrostatic field solver of the gyrokinetic full-f PIC code PICLS. The solver makes use of a Fourier representation in one periodi…
Gyrokinetic simulations of turbulence and zonal flows driven by steep profile gradients using a delta-f approach with an evolving background Maxwellian
Moahan Murugappan, Laurent Villard, Stephan Brunner +2
Long global gyrokinetic turbulence simulations are particularly challenging in situations where the system deviates strongly from its initial state and when fluctuation level are h…
