Direct Comparison of Gyrokinetic and Fluid Scrape-Off Layer Simulations
A. Shukla, J. Roeltgen, M. Kotschenreuther +7
Typically, fluid simulations are used for tokamak divertor design. However, fluid models are only valid if the SOL is highly collisional, an assumption that is valid in many presen…
Kinetic modeling of neutral transport for a continuum gyrokinetic code
T. N. Bernard, F. D. Halpern, M. Francisquez +6
We present the first-of-its-kind coupling of a continuum full-f gyrokinetic turbulence model with a 6D continuum model for kinetic neutrals, carried out using the Gkeyll code. Our…
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,…
Fluid & Gyrokinetic turbulence in open field-line, helical plasmas
Manaure Francisquez, Tess N. Bernard, Ben Zhu +3
Two-fluid Braginskii codes have simulated open-field line turbulence for over a decade, and only recently has it become possible to study these systems with continuum gyrokinetic c…
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…
