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,…
Discontinuous Galerkin schemes for a class of Hamiltonian evolution equations with applications to plasma fluid and kinetic problems
A. Hakim, G. Hammett, E. Shi +1
In this paper we present energy-conserving, mixed discontinuous Galerkin (DG) and continuous Galerkin (CG) schemes for the solution of a broad class of physical systems described b…
Gyrokinetic continuum simulations of plasma turbulence in the Texas Helimak
Tess N. Bernard, Eric L. Shi, Kenneth Gentle +4
The first gyrokinetic simulations of plasma turbulence in the Texas Helimak device, a simple magnetized torus, are presented. The device has features similar to the scrape-off laye…
Full- gyrokinetic simulation of turbulence in a helical open-field-line plasma
Eric L. Shi, Gregory W. Hammett, Timothy Stoltzfus-Dueck +1
Curvature-driven turbulence in a helical open-field-line plasma is investigated using electrostatic five-dimensional gyrokinetic continuum simulations in an all-bad-curvature helic…
Gyrokinetic Continuum Simulation of Turbulence in Open-Field-Line Plasmas
E. L. Shi
The properties of the boundary plasma in a tokamak are now recognized to play a key role in determining the achievable fusion power and the lifetimes of plasma-facing components. A…
Discontinuous Galerkin algorithms for fully kinetic plasmas
J. Juno, A. Hakim, J. TenBarge +2
We present a new algorithm for the discretization of the Vlasov-Maxwell system of equations for the study of plasmas in the kinetic regime. Using the discontinuous Galerkin finite…
