Investigation of a Multiple-Timescale Turbulence-Transport Coupling Method in the Presence of Random Fluctuations
Jeffrey B. Parker, Lynda L. LoDestro, Alejandro Campos
One route to improved predictive modeling of magnetically confined fusion reactors is to couple transport solvers with direct numerical simulations (DNS) of turbulence, rather than…
Magnetic suppression of zonal flows on a beta plane
Navid C. Constantinou, Jeffrey B. Parker
Zonal flows in rotating systems have been previously shown to be suppressed by the imposition of a background magnetic field aligned with the direction of rotation. Understanding t…
Bringing global gyrokinetic turbulence simulations to the transport timescale using a multiscale approach
Jeffrey B. Parker, Lynda L. LoDestro, Daniel Told +5
The vast separation dividing the characteristic times of energy confinement and turbulence in the core of toroidal plasmas makes first-principles prediction on long timescales extr…
Numerical simulation of the geometrical-optics reduction of CE2 and comparisons to quasilinear dynamics
Jeffrey B. Parker
Zonal flows have been observed to appear spontaneously from turbulence in a number of physical settings. A complete theory for their behavior is still lacking. Recently, a number o…
