Reduction of transport due to magnetic shear in gyrokinetic simulations of the scrape-off layer
N. R. Mandell, G. W. Hammett, A. Hakim +1
The effect of varying magnetic shear on scrape-off layer turbulence and profiles is studied via electromagnetic gyrokinetic simulations of a helical scrape-off layer model. We deve…
Turbulent broadening of electron heat-flux width in electromagnetic gyrokinetic simulations of a helical scrape-off layer model
N. R. Mandell, G. W. Hammett, A. Hakim +1
We demonstrate that cross-field transport in the scrape-off layer (SOL) can be moderately increased by electromagnetic effects in high-beta regimes, resulting in a broader electron…
Mapped discontinuous Galerkin interpolations and sheared boundary conditions
Manaure Francisquez, Noah R. Mandell, Ammar Hakim +1
Translations or, more generally, coordinate transformations of scalar fields arise in several applications, such as weather, accretion disk and magnetized plasma turbulence modelin…
Improved multispecies Dougherty collisions
Manaure Francisquez, James Juno, Ammar Hakim +2
The Dougherty model Fokker-Planck operator is extended to describe nonlinear full-f collisions between multiple species in plasmas. Simple relations for cross-species interactions…
