Neoclassical Transport Modeling Compatible with a Two-Fluid Transport Equation System

Abstract

A neoclassical transport model compatible with a system of two-fluid equations is proposed, with an emphasis on the heat flux contribution. The model is based on the moment approach and is capable of accurately reproducing important neoclassical properties through a simple expression of the neoclassical viscosity tensor, with the aid of the NCLASS module. Applying neoclassical transport theory in a fluid context, we confirm the reproducibility of first-order flows, poloidal flows, neoclassical resistivity, bootstrap current and particle flux.
