Alias-free, matrix-free, and quadrature-free discontinuous Galerkin algorithms for (plasma) kinetic equations
Ammar Hakim, James Juno
Understanding fundamental kinetic processes is important for many problems, from plasma physics to gas dynamics. A first-principles approach to these problems requires a statistica…
Investigating shear flow through continuum gyrokinetic simulations of limiter biasing in the Texas Helimak
Tess N. Bernard, Timothy Stoltzfus-Dueck, Kenneth W. Gentle +3
Previous limiter-biasing experiments on the Texas Helimak, a simple magnetized torus, have been inconclusive on the effect of flow shear on turbulence levels. To investigate this,…
Fluid & Gyrokinetic turbulence in open field-line, helical plasmas
Manaure Francisquez, Tess N. Bernard, Ben Zhu +3
Two-fluid Braginskii codes have simulated open-field line turbulence for over a decade, and only recently has it become possible to study these systems with continuum gyrokinetic c…
Dynamo in weakly collisional nonmagnetized plasmas impeded by Landau damping of magnetic fields
István Pusztai, James Juno, Axel Brandenburg +4
We perform fully kinetic simulations of flows known to produce dynamo in magnetohydrodynamics (MHD), considering scenarios with low Reynolds number and high magnetic Prandtl number…
Exact and Locally Implicit Source Term Solvers for Multifluid-Maxwell Systems
Liang Wang, Ammar Hakim, Jonathan Ng +2
Recently, a family of models that couple multifluid systems to the full Maxwell equations draw a lot of attention in laboratory, space, and astrophysical plasma modeling. These mod…
Boundary Conditions for Continuum Simulations of Wall-bounded Kinetic Plasmas
Petr Cagas, Ammar Hakim, Bhuvana Srinivasan
Continuum kinetic simulations of plasmas, where the distribution function of the species is directly discretized in phase-space, permits fully kinetic simulations without the stati…
