Towards continuum gyrokinetic study of high-field mirrors
Manaure Francisquez, Maxwell H. Rosen, Noah R. Mandell +3
High-temperature superconducting (HTS) magnetic mirrors under development exploit strong fields with high mirror ratio to compress loss cones and enhance confinement, and may offer…
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…
Scrape-Off Layer Turbulence in Tokamaks Simulated with a Continuum Gyrokinetic Code
A. Hakim, E. L. Shi, I. G. Abel +2
We are developing a new continuum gyrokinetic code, Gkeyll, for use in edge plasma simulations, and here present initial simulations of turbulence on open field lines with model sh…
Continuum Kinetic and Multi-Fluid Simulations of Classical Sheaths
Petr Cagas, Ammar Hakim, James Juno +1
The kinetic study of plasma sheaths is critical, among other things, to understand the deposition of heat on walls, the effect of sputtering, and contamination of the plasma with d…
Two-Dimensional Modeling of Ideal Merging Plasma Jets
John Loverich, Ammar Hakim
Idealized merging argon plasma jets are simulated in 2D using both gas dynamic and MHD models. Results indicate that peak pressures of several hundred kilobar can be achieved for h…
FACETS - a Framework for Parallel Coupling of Fusion Components
John R. Cary, Ammar Hakim, Mahmood Miah +12
Coupling separately developed codes offers an attractive method for increasing the accuracy and fidelity of the computational models. Examples include the earth sciences and fusion…
