Computatinal study of iter-like dissipative divertor plasma in the collisional limit

摘要

A two dimensional(2-D)combined edge plasma/Navier-Stokes neutral transport model is used in a computational study of dissipative divertor plasmas in the collisional limit for neutrals, with ITER-like plasma conditions and scale lengths. The neutral model contains three momentum equations that are coupled to the plasma through ionization, recombination and ion- neutral elastic collisions. The neutral transport coefficients are evaluated including both ion-neutral and neutral-neutral collisions. The structure of fully detached plasma solutions is studied for ITER plasma conditions.
