Abstract
The theory of the fluctuation-driven radial electric field in toroidal geometry is presented. It is shown that the gyro-viscosity as well as the poloidal pressure gradient and parallel inertia provide significa nt contributions to the generation of the radial electric field. The n eoclassical parallel viscosity modified by the inertia terms and fluct uation-driven transport is evaluated. The equations for the rotation o f a turbulent tokamak plasma are derived.
