Revisited neoclassical transport theory for steep, collisional plasma edge profiles
It is shown that existing neoclassical theories in the high collisionality regime are inadequate to describe the edge plasma, where the gradient length scales are of the order of only a few centimetres. Gyrostresses usually modify considerably the continuity, energy, and parallel momentum equations. Particle transport, moreover, is no longer automatically ambipolar: the radial electric field is actually determined by the ambipolarity constraint.
