Abstract

Tokamak edge plasma transport in a diverted geometry is studied employing Braginskii type two dimensional transport simulation and drift wave turbulence simulation. The two models are connected through local perpendicular transport coefficients. The basic idea behind is to replace fast time scale, repetitive turbulence vortex dynamics by a diffusion operator. To this end, parameterization of transport coefficients D and χ is introduced. The transport is determined by the gradient drives inside the separatrix and non-adiabatic electron response induced by high collisionality in the low temperature open-magnetic-field-line regions.
