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…
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…
Magnetic shear effects on ballooning turbulence in the boundary of fusion devices
Z. Tecchiolli, A. J. Coelho, J. Loizu +2
The effect of magnetic shear on ballooning-driven plasma edge turbulence is studied through nonlinear simulations complemented by linear numerical and analytical investigations. No…
Constructing nested coordinates inside strongly shaped toroids using an action principle
Zeno Tecchiolli, Stuart Hudson, Joaquim Loizu +3
A new approach for constructing polar-like boundary-conforming coordinates inside a toroid with strongly shaped cross-sections is presented. A coordinate mapping is obtained throug…
