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…
Derivation and application of sheath boundary conditions for drift-kinetic simulations in a linear plasma device based on a gyromoment approach
Jacob Emil Mencke, Thomas Stucker, Paolo Ricci
Boundary conditions for a drift-kinetic model at the collisional presheath entrance with perpendicular incidence of the magnetic field to the wall are derived and numerically imple…
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…
Comprehensive full-f drift-kinetic and delta-f gyrokinetic simulations of a linear plasma device based on the gyro-moment approach
Jacob Emil Mencke, Paolo Ricci
First of a kind comprehensive full-f drift-kinetic (DK) and -f gyrokinetic (GK) turbulent simulations are carried out in a linear plasma device. We self-consistently derive an e…
Conservative formulation of the drift-reduced fluid plasma model
Brenno De Lucca, Paolo Ricci, Micol Bassanini +2
A conservative formulation of the drift-reduced fluid plasma model is constructed by analytically inverting the implicit relation defining the polarisation velocity as a function o…
The hot-electron closure of the moment-based gyrokinetic plasma model
A. C. D. Hoffmann, P. Giroud-Garampon, P. Ricci
We derive the hot-electron-limit (HEL) closure for the moment hierarchy used to solve the gyrokinetic equations, known as the gyromoment (GM) approach. By expanding the gyroaveragi…
Investigation of triangularity effects on tokamak edge turbulence through multi-fidelity gyrokinetic simulations
A. C. D. Hoffmann, P. Ricci
This paper uses the gyro-moment (GM) approach as a multi-fidelity tool to explore the effect of triangularity on tokamak edge turbulence. Considering experimental data from an L-mo…
