Comparison of neoclassical rotation theory with experiment under a variety of conditions in DIII-D
(Georgia Institute of Technology, 2002-03)
A neoclassical theory of gyroviscous radial momentum transport and poloidal and toroidal rotation has been compared with experiment in DIII-D discharges in different confinement regimes, with a range of neutral beam powers ...
A framework for the development and testing of an edge pedestal model: formulation and initial comparison with DIII-D data
(Georgia Institute of Technology, 2003-06)
A framework has been formulated for the further development and testing of a predictive edge pedestal model. This framework combines models for the interaction of the various physical phenomena acting in the edge ...
The effects of rotation, electric field, and recycling neutrals on determining the edge pedestal density profile
(Georgia Institute of Technology, 2010-05-19)
The edge density profile is calculated from the continuity and momentum balance equations, using experimental electric field and rotation velocities and a calculated recycling neutral source, to evaluate the relative ...
An edge pedestal model based on transport and atomic physics
(Georgia Institute of Technology, 2001-09)
A model is presented for the calculation of the characteristic scale lengths from transport considerations in the edge pedestal region of high confinement (H-mode) plasmas. The model is based on the requirements of heat ...
Poloidal rotation, density asymmetries, and momentum confinement in tokamak experiments
(Georgia Institute of Technology, 1993-06)
Poloidal rotation speeds and density asymmetries are calculated for the deuterium and dominant carbon (oxygen) impurity ions in discharges in the Axially Symmetric Divertor Experiment (ASDEX) [Proceedings of the 13th ...
Poloidal rotation and density asymmetries in a tokamak plasma with strong toroidal rotation
(Georgia Institute of Technology, 1992-10)
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 ...
