Recent Progress of Boundary Plasma Research 5.Recent Progress of Boundary Plasma Modeling in Tokamak

Abstract

The numerical modeling of tokamak divertor plasmas and recent related topics have been briefly reviewed. Among the various simulation models, main attention is placed on the fluid model of plasmas and the Monte-Carlo model of neutrals. The following two recent topics are mainly discussed: i) the modeling of excited neutrals and MAR (Molecular Activated Recombination), and ii) plasma flow in the detachment plasma.
