摘要：

A two-dimensional combined edge plasma Navier-Stokes neutral transport model is presented for the simulation of dense recombining divertor plasmas. This model includes ions, electrons, and neutral atoms which undergo Coulomb collisions, electron impact ionization, ion-neutral elastic collisions, three-body and radiative recombination, and neutral-neutral collisions, The advanced fully implicit solution algorithm is briefly described and a variety of results on a model geometry are presented. It is shown that interesting neutral flow patterns can exist and that these flows can convect significant energy. A solution that ignores neutral-neutral collisions is shown to be quantitatively different from one that includes neutral-neutral collisions. Solutions are also shown to be sensitive to the plasma opacity for Lyman alpha radiation. (C) 1996 American Institute of Physics.
