Abstract
Scrape-off layer parallel flows and the viscous fluxes in the plasma edge driven thereby are
calculated from neoclassical theory for a model problem representative of a present experiment,
using an analytical model for elongated flux surface geometry with a Shafranov shift to provide a
realistic evaluation of important poloidal dependences. The estimated effects of the viscous torques
of toroidal and poloidal momentum driven by these scrape-off layer flows on rotation velocities in
the edge plasma are substantial, suggesting possible explanations for various experimental
observations.
