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…
