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…
Radially global computation of neoclassical phenomena in a tokamak pedestal
Matt Landreman, Felix I Parra, Peter J Catto +2
Conventional radially-local neoclassical calculations become inadequate if the radial gradient scale lengths of the H-mode pedestal become as small as the poloidal ion gyroradius.…
New velocity-space discretization for continuum kinetic calculations and Fokker-Planck collisions
Matt Landreman, Darin R. Ernst
Numerical techniques for discretization of velocity space in continuum kinetic calculations are described. An efficient spectral collocation method is developed for the speed coord…
Local and global Fokker-Planck neoclassical calculations showing flow and bootstrap current modification in a pedestal
Matt Landreman, Darin R. Ernst
In transport barriers, particularly H-mode edge pedestals, radial scale lengths can become comparable to the ion orbit width, causing neoclassical physics to become radially nonloc…
Changes to neoclassical flow and bootstrap current in a tokamak pedestal
Matt Landreman, Darin R. Ernst
In a tokamak pedestal, radial scale lengths can become comparable to the ion orbit width, invalidating conventional neoclassical calculations of flow and bootstrap current. In this…
