- Abstract
- A two-dimensional axisymmetric numerical code is developed for the simulation of
a Hall thruster plume operating in various ambient plasmas. The code is based on
a combination of particle simulation for the ionic components (Xe+ and Xe++) and
fluid computational techniques for electrons. In particular we have used the
Boltzmann relation modified in order to allow for the effect of non isothermal
electron temperature based on the adiabatic approximation. In our model, several
solutions which have been sparsely considered in previous works are jointly
adopted. In particular: the electric field is computed by solving the Poisson equation
without assuming quasi-neutrality, which often is violated in the near-field plume
region; and collision processes are included by using two new techniques, the
ion-neutral Test-Particle Monte Carlo collision model and the Nanbu cumulative
small-angle collision theory for ion-ion coulombic collisions. Comparisons with
experimental data suggest that the present simulation is accurately modeling the
physics of the very-near-field region of the plume. (literal)
