Implicit-Explicit time integration scheme with Physics-based preconditioning for two-fluid tokamak boundary simulations
Micol Bassanini, Simone Deparis, Paolo Ricci +4
In this work, a globally stiffly accurate Implicit-Explicit (IMEX) Runge-Kutta scheme is developed and implemented in the GBS code [Ricci et al., Plasma Phys. Control. Fusion, 2012…
On energy conservation laws in the drift-reduced Braginskii model
Sergio García Herreros, Brenno de Lucca, Davide Mancini +5
A revision of the drift-reduced Braginskii model is presented, focusing on its practical implementation in numerical codes, and systematically analyzing the effect of several commo…
Theory for the power threshold of the L-H transition in tokamaks
Brenno De Lucca, Paolo Ricci, Benoit Labit +3
Flux-driven two-fluid simulations in a diverted tokamak exhibit a confinement transition when a critical heating threshold is exceeded, as in experimental observations of the L-H t…
Predictive power-sharing scaling law in double-null L-mode plasmas
K. Lim, P. Ricci, L. Stenger +5
The physical mechanisms regulating the power sharing at the outer targets of L-mode double-null (DN) configurations are investigated using nonlinear, flux-driven, three-dimensional…
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…
The GBS code for the self-consistent simulation of plasma turbulence and kinetic neutral dynamics in the tokamak boundary
M. Giacomin, P. Ricci, A. Coroado +7
A new version of GBS (Ricci et al. Plasma Phys. Control. Fusion 54, 124047, 2012; Halpern et al. J. Comput. Phys. 315, 388-408, 2016; Paruta et al. Phys. Plasmas 25, 112301, 2018)…
Development of Advanced Linearized Gyrokinetic Collision Operators Using a Moment Approach
B. J. Frei, J. Ball, A. C. D. Hoffmann +3
The derivation and numerical implementation of a linearized version of the gyrokinetic (GK) Coulomb collision operator (Jorge R. et al., J. Plasma Phys. 85, 905850604 (2019)) and o…
