Drift-reduced fluid modeling of rapidly rotating plasmas
Edward A. Tocco, Benjamin D. Dudson, Ian G. Abel +1
In this paper, we investigate the effects of rapid rotation (Mach number M ~ 1) on plasma fluid stability, focusing specifically on Kelvin-Helmholtz (KH) and interchange instabilit…
A Propagator-based Multi-level Monte Carlo Method for Kinetic Neutral Species in Edge Plasmas
Gregory J. Parker, Maxim V. Umansky, Benjamin D. Dudson
We propose and investigate a new multi-level Monte Carlo scheme for numerical solutions of the kinetic Boltzmann equation for neutral species in edge plasmas. In particular, this m…
Modeling of convective cells, turbulence, and transport induced by a radio-frequency antenna in the tokamak boundary plasma
M. V. Umansky, B. D. Dudson, T. G. Jenkins +2
The edge turbulence model Hermes (Dudson et al., 2017 Plasma Phys. Control. Fusion 59 05401) is set up for plasma boundary simulations with an RF antenna, using parameters characte…
Coupling Fluid Plasma and Kinetic Neutral Models using Correlated Monte Carlo Methods
Gregory J. Parker, Maxim V. Umansky, Benjamin D. Dudson
While boundary plasmas in present-day tokamaks generally fall in a fluid regime, neutral species near the boundary often require kinetic models due to long mean-free-paths compared…
