TL;DR: In this paper, a systematic decomposition of the physical processes which drive intrinsic rotation, a calculation of the critical external torque necessary to hold the plasma stationary against the intrinsic residual stress, a simple model of net velocity scaling which recovers the salient features of the experimental trends and the elucidation of the impact of the particle flux on the net toroidal velocity pinch are offered.

TL;DR: A general geometry gyro-kinetic model for particle simulation of plasma turbulence in tokamak experiments is described in this paper, which incorporates the comprehensive influence of noncircular cross section, realistic plasma profiles, plasma rotation, neoclassical (equilibrium) electric fields, and Coulomb collisions.

TL;DR: An overview of the physics of intrinsic torque is presented, with special emphasis on the phenomenology of intrinsic toroidal rotation in tokamaks, its theoretical understanding, and the variety of momentum transport bifurcation dynamics as discussed by the authors.

TL;DR: In this paper, the NSTX plasmas are heated by up to 7 MW of deuterium neutral beams with preferential electron heating as expected for ITER, and a strong increase in confinement with decreasing collisionality and a weak degradation with beta.

TL;DR: In this paper, a nonlinear residual stress generation by both fluctuation intensity and the intensity gradient in the presence of broken symmetry in the parallel wavenumber spectrum is identified for the first time.
