Gyrofluid Magnetic Reconnection Beyond the δ F Approximation
F. F. Locker, M. Rinner, M. Held +1
Magnetic reconnection in a two-dimensional system is studied employing a novel Full-F gyrofluid model with arbitrary- wavelength polarization. In strongly magnetized plasmas, the l…
GREENY: A Full-F 2D Gyrofluid Reconnection Code
F. F. Locker, M. Held, T. Stocker-Waldhuber +3
We present the 2D gyrofluid magnetic reconnection code GREENY (Gyrofluid Reconnection with Extended Electromagnetic Nonlinearity). After a brief introduction to gyrofluids, magneti…
Effects of plasma resistivity in three-dimensional full-F gyro-fluid turbulence simulations
M. Wiesenberger, M. Held
A full-F, isothermal, electromagnetic, gyro-fluid model is used to simulate plasma turbulence in a COMPASS-sized, diverted tokamak. A parameter scan covering three orders of magnit…
Beyond the Oberbeck-Boussinesq and long wavelength approximation
Markus Held, Matthias Wiesenberger
We present the first simulations of a reduced magnetized plasma model that incorporates both arbitrary wavelength polarization and non-Oberbeck-Boussinesq effects. Significant infl…
Angular momentum and rotational energy of meanflows in toroidal magnetic fields
Matthias Wiesenberger, Markus Held
We derive the balance equation for the Favre averaged angular momentum in toroidal not necessarily axisymmetric magnetic field equilibria. We find that the components of angular mo…
Padé-based arbitrary wavelength polarization closures for full-F gyro-kinetic and -fluid models
Markus Held, Matthias Wiesenberger, Alexander Kendl
We propose a solution to the long-standing short wavelength polarization closure shortfall of full-F gyro-fluid models. This is achieved by first finding an appropriate quadratic f…
