Ion temperature gradient mode mitigation by energetic particles, mediated by forced-driven zonal flows
Juvert Njeck Sama, Alessandro Biancalani, Alberto Bottino +14
In this work, we use the global electromagnetic and electrostatic gyro kinetic approaches to investigate the effects of zonal flows forced-driven by Alfvén modes due to their excit…
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…
Locality properties of the free energy fluxes in gyrokinetic turbulence
Bogdan Teaca, Alejandro Banon Navarro, Frank Jenko +2
The nature of the nonlinear interactions in gyrokinetic (GK) turbulence, driven by an ion-temperature gradient instability, is investigated using numerical simulations of single io…
