Poloidal Rotation and Density Asymmetries in a Tokamak Plasma with StrongToroidal Rotation

摘要

A neoclassical model for calculating poloidal rotation and poloidal densityasymmetries in a tokamak plasma with V(sub phi) approx equal V(sub th) and E/B(sub theta) approx equal 0(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 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.
