A self-consistent multi-component model of plasma turbulence and kinetic neutral dynamics for the simulation of the tokamak boundary

A self-consistent model is presented for the simulation of a multi-component plasma in tokamak boundary. deuterium considered, with species that include electrons, atomic ions and molecular ions, while atoms molecules constitute neutral species. The models are coupled via number collisional interactions, which dissociation, ionization, charge-exchange recombination processes. derivation three-fluid drift-reduced Braginskii equations used to describe turbulent dynamics presented, including its boundary conditions. kinetic advection also derived, their numerical implementation discussed. first results simulations carried out by using GBS code then analyzed, being compared obtained single-component model.
