Low-dimensional geometry learning for turbulence prediction in optimized stellarators
Xishuo Wei, Handi Huang, Haotian Chen +4
The optimized stellarator is an attractive concept for which the averaged particle radial drift is zero, and the single particle loss can be significantly reduced. But for the reac…
Detecting Shearless Phase-Space Transport Barriers in Global Gyrokinetic Turbulence Simulations with Test Particle Map Models
Norman M. Cao, Hongxuan Zhu, Gabriel C. Grime +1
In magnetically confined fusion plasmas, the role played by zonal EB flow shear layers in the suppression of turbulent transport is relatively well-understood. However, les…
Global linear drift-wave eigenmode structures on flux surfaces in stellarators: ion temperature gradient mode
Hongxuan Zhu, H. Chen, Z. Lin +1
Turbulent transport greatly impacts the performance of stellarator magnetic confinement devices. While significant progress has been made on the numerical front, theoretical unders…
Geometry effects on zonal flow dynamics and turbulent transport in optimized stellarators
Haotian Chen, Xishuo Wei, Hongxuan Zhu +1
Global gyrokinetic simulations find a strong suppression of ion temperature gradient (ITG) turbulence by zonal flows in stellarators optimized for neoclassical transport. The reduc…
Collisionless zonal-flow dynamics in quasisymmetric stellarators
Hongxuan Zhu, Z. Lin, A. Bhattacharjee
The linear collisionless plasma response to a zonal-density perturbation in quasisymmetric stellarators is studied, including the geodesic-acoustic-mode oscillations and the Rosenb…
Intrinsic toroidal rotation driven by turbulent and neoclassical processes in tokamak plasmas from global gyrokinetic simulations
Hongxuan Zhu, T. Stoltzfus-Dueck, R. Hager +2
Gyrokinetic tokamak plasmas can exhibit intrinsic toroidal rotation driven by the residual stress. While most studies have attributed the residual stress to the parallel-momentum f…
