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…
Freely decaying turbulence in two-dimensional electrostatic gyrokinetics
T. Tatsuno, G. G. Plunk, M. Barnes +3
In magnetized plasmas, a turbulent cascade occurs in phase space at scales smaller than the thermal Larmor radius ("sub-Larmor scales") [Phys. Rev. Lett. 103, 015003 (2009)]. When…
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…
Spectral stability of periodic wave trains of the Korteweg-de Vries/Kuramoto-Sivashinsky equation in the Korteweg-de Vries limit
Mathew A. Johnson, Pascal Noble, L. Miguel Rodrigues +1
We study the spectral stability of a family of periodic wave trains of the Korteweg-de Vries/Kuramoto-Sivashinsky equation $ \partial_t v+v\partial_x v+\partial_x^3 v+δ(\partial_x^…
Hamiltonian magnetohydrodynamics: symmetric formulation, Casimir invariants, and equilibrium variational principles
Tommaso Andreussi, Philip J. Morrison, Francesco Pegoraro
The noncanonical Hamiltonian formulation of magnetohydrodynamics (MHD) is used to construct variational principles for symmetric equilibrium configurations of magnetized plasma inc…
