A previous model for the calculation of poloidal velocities and poloidal density asymmetries in the core of a tokamak plasma is refined and extended by the inclusion of terms which are important for the calculation of these quantities in the plasma edge. Agreement of predictions of the model with experiment is demonstrated. The effects of edge pressure gradient, collisionality, neutral density and up–down flux surface asymmetry on the edge poloidal rotation velocities are illustrated by a series of model problem calculations.

A model for the edge pedestal in high-confinement mode tokamak plasmas is described. Separate gradient scale lengths of the density and of the ion and electron temperatures are calculated from transport and atomic physics considerations, and a common pedestal width is calculated from either a magnetohydrodynamic pedestal β-limit or from neutral penetration considerations. Predictions of the model for a representative gas fueled tokamak model problem are discussed vis-à-vis measured values of pedestal gradient scale lengths and widths, ballooning mode limits, and scaling with operational parameters
