Poloidal rotation and density asymmetries in a tokamak plasma with strong toroidal rotation

A neoclassical model for calculating poloidal rotation and poloidal density asymmetries in a tokamak plasma with vφ∼vth and E/Bθ∼O(1) is developed. Application is made to the analysis of a deuterium plasma with a dominant carbon impurity. The dependences of the results on collisionality, the anomalous radial deuterium flux and the toroidal rotation speed are evaluated. The implications of the calculated poloidal velocities and density asymmetries for the magnitude of the gyroviscous torque are discussed.
