Verification of long wavelength electromagnetic modes with a gyrokinetic-fluid hybrid model in the XGC code
Robert Hager, Jianying Lang, Choong-Seock Chang +4
As an alternative option to kinetic electrons, the gyrokinetic total-f particle-in-cell (PIC) code XGC1 has been extended to the MHD/fluid type electromagnetic regime by combining…
Moment Preserving Constrained Resampling with Applications to Particle-in-Cell Methods
Danial Faghihi, Varis Carey, Craig Michoski +4
In simulations of partial differential equations using particle-in-cell (PIC) methods, it is often advantageous to resample the particle distribution function to increase simulatio…
Electrostatic gyrokinetic simulation of global tokamak boundary plasma and the generation of nonlinear intermittent turbulence
S. Ku, R. M. Churchill, C. S. Chang +5
Boundary plasma physics plays an important role in tokamak confinement, but is difficult to simulate in a gyrokinetic code due to the scale-inseparable nonlocal multi-physics in ma…
A fast low-to-high mode bifurcation dynamics in a tokamak edge plasma gyrokinetic simulation
C. S. Chang, S. Ku, G. R. Tynan +6
Transport barrier formation and its relation to sheared flows in fluids and plasmas are of fundamental interest in various natural and laboratory observations and of critical impor…
