Abstract

The poloidal and parallel plasma viscosities in tokamak geometry in Hamada coordinates are calculated from the drift kinetic equation, including a large mass flow velocity without imposing the usual constraint that VpB /(υtiBp) be small. Here, Vp is the poloidal plasma flow velocity, υti is the ion thermal speed, B is the magnetic field strength, and Bp is the poloidal magnetic field strength. With this extended validity, the poloidal and parallel viscosities are useful in modeling the radial electric field in the edge region of a tokamak in the enhanced confinement regime.
