Gyrokinetic moment-based simulations of the Dimits shift
A. C. D. Hoffmann, B. J. Frei, P. Ricci
We present a convergence study of the gyromoment (GM) approach, which is based on projecting the gyrokinetic distribution function onto a Hermite-Laguerre polynomial basis, focused…
Full-F Turbulent Simulation in a Linear Device using a Gyro-Moment Approach
B. J. Frei, J. Mencke, P. Ricci
Simulations of plasma turbulence in a linear plasma device configuration are presented. These simulations are based on a simplified version of the gyrokinetic (GK) model proposed b…
Effect of triangularity on plasma turbulence and the SOL-width scaling in L-mode diverted tokamak configurations
Kyungtak Lim, Maurizio Giacomin, Paolo Ricci +5
The effect of triangularity on tokamak boundary plasma turbulence is investigated by using global, flux-driven, three-dimensional, two-fluid simulations. The simulations show that…
Validation of GBS plasma turbulence simulation of the TJ-K stellarator
A. J. Coelho, J. Loizu, P. Ricci +4
We present a validation of a three-dimensional, two-fluid simulation of plasma turbulence in the TJ-K stellarator, a low temperature plasma experiment ideally suited for turbulence…
Moment-Based Approach to the Flux-Tube linear Gyrokinetic Model
B. J. Frei, A. C. D. Hoffmann, P. Ricci +2
This work reports on the development and numerical implementation of the linear electromagnetic gyrokinetic (GK) model in a tokamak flux-tube geometry using a moment approach based…
Gyrokinetic simulations of plasma turbulence in a Z-pinch using a moment based approach and advanced collision operators
A. C. D. Hoffmann, B. J. Frei, P. Ricci
The first nonlinear gyrokinetic simulations obtained using a moment approach based on the Hermite-Laguerre decomposition of the distribution function are presented, implementing ad…
