Extension and comparison of neoclassical models for poloidal rotation in tokamaks
Stacey, Weston M.
MetadataShow full item record
Several neoclassical models for the calculation of poloidal rotation in tokamaks were rederived within a common framework, extended to include additional physics and numerically compared. The importance of new physics phenomena not usually included in poloidal rotation calculations e.g., poloidal electric field, V B force resulting from enhanced radial particle flow arising from the ionization of recycling neutrals was examined. Extensions of the Hirshman–Sigmar, Kim–Diamond–Groebner, and Stacey–Sigmar poloidal rotation models are presented.
