Modeling Electron Transport within the Framework of Hydrodynamic Description of Hall Thrusters (Preprint)

Abstract

In this paper we consider kinetic effects related to electron transport in the framework on hydrodynamic model of the plasma flow inside the Hall thruster channel. In particular, kinetics of the near wall conductivity (NWC) is analyzed and analytical expression is derived that takes into account the sheath effects. The NWC model is incorporated into the hydrodynamic model. In addition we consider an effect of SEE electron thermalization. It is found that current predicted by the analytical model can provide reasonable solution without any fitting parameters.
