Characterization of reduced-order turbulence models in the L-mode pedestal-forming region in JET
G. Snoep, C. Bourdelle, J. Citrin +7
Linear instability characterization of seven JET discharges just prior to the L-H transition is performed at with the gyrokinetic GENE code. Th…
Suppressing Trapped-Electron-Mode-Driven Turbulence via Optimization of Three-Dimensional Shaping
J. M. Duff, B. J. Faber, C. C. Hegna +2
Turbulent transport driven by trapped electron modes (TEMs) is believed to drive significant heat and particle transport in quasihelically symmetric stellarators. Two three-dimensi…
Importance of theory, computation and predictive modeling in the US magnetic fusion energy strategic plan
Fatima Ebrahimi, Gary Staebler, Paul Bonoli +5
Based on the community input at the National Academy of Sciences (NAS) Madison and Austin workshops in July and December 2017, respectively, this whitepaper was prepared and submit…
The impact of magnetic fields on momentum transport and saturation of shear-flow instability by stable modes
A. E. Fraser, P. W. Terry, E. G. Zweibel +2
The Kelvin-Helmholtz (KH) instability of a shear layer with an initially-uniform magnetic field in the direction of flow is studied in the framework of 2D incompressible magnetohyd…
Suppression of turbulence by trapped electrons in optimised stellarators
J. H. E. Proll, P. Xanthopoulos, P. Helander +5
In fusion devices, the geometry of the confining magnetic field has a significant impact on the instabilities that drive turbulent heat loss. This is especially true of stellarator…
Role of stable modes in driven shear-flow turbulence
A. E. Fraser, M. J. Pueschel, P. W. Terry +1
A linearly unstable, sinusoidal shear flow is examined in the gyrokinetic framework in both the linear and nonlinear regimes. In the linear regime, it is shown that th…
