Intrinsic toroidal rotation in a tokamak can be driven by turbulent momentum transport due to neoclassical flow effects breaking a symmetry of turbulence. In this paper we categorize the contributions due to neoclassical effects to the turbulent momentum transport, and evaluate each contribution using gyrokinetic simulations. We find that the relative importance of each contribution changes with collisionality. For low collisionality, the dominant contributions come from neoclassical particle… 

Intrinsic rotation driven by turbulent acceleration

Differential rotation is induced in tokamak plasmas when an underlying symmetry of the governing gyrokinetic-Maxwell system of equations is broken. One such symmetry-breaking mechanism is considered

Intrinsic rotation in tokamaks: theory

Self-consistent equations for intrinsic rotation in tokamaks with small poloidal magnetic field Bp compared to the total magnetic field B are derived. The model gives the momentum redistribution due

The impact of the neoclassical background on turbulent impurity transport is investigated by means of gyrokinetic simulations supported by fluid equations. The latter are derived, using a Laguerre

Cross-Coupling of Gyrokinetic Turbulence and the Neoclassical Equilibrium in Tokamak Plasmas

Small scale turbulence in a magnetically confined fusion plasma is the major loss channel for energy and critically limits the confinement. This thesis investigates the interactions between the

In this paper, the theory of collisional and turbulent transport of impurities in tokamak plasmas is reviewed. The results are presented with the aim of providing at the same time a historical

DIII-D shaping demonstrates correlation of intrinsic momentum with energy

Scaling of intrinsic rotation in DIII-D H-mode plasmas demonstrates a strong correlation with the ion temperature (Ti) and stored plasma thermal energy, indicating a coupling between the turbulent

A collisionality-dependent transition from peaked to hollow rotation profiles, consistent with experimental observations of intrinsic rotation, is indicated.

Toroidal momentum transport in a tokamak due to profile shearing

The effect of profile shearing on toroidal momentum transport is studied in linear and non-linear gyro-kinetic simulations. Retaining the radial dependence of both plasma and geometry parameters

Anomalous parallel momentum transport due to E×B flow shear in a tokamak plasma

Nondiffusive anomalous momentum transport in toroidal plasmas occurs through symmetry breaking mechanisms. In this paper the contribution of sheared E X B flows to parallel momentum transport [R. R.
