The current status and challenges of the discharge plasma modeling capabilities in Hall
effect thrusters (HETs) are reviewed. Partially magnetized plasmas in HETs present unique …

Rotating spoke phenomena have been observed in a variety of Hall thruster and other E× B
devices. It has been suggested that the spoke may be associated with the enhancement of …

Fluid models of the slow-dynamics of magnetized, weakly-collisional electrons lead to build
computationally-affordable, long-time simulations of plasma discharges in Hall-effect and …

Low-frequency ionization oscillations involving plasma and neutral density (breathing
modes) are the most violent perturbations in Hall thrusters for electric propulsion. Because of …

In wall-less Hall thrusters, the ionization of the propellant and the acceleration of the ions
occur outside the thruster [S. Mazouffre, S. Tsikata, and J. Vaudolon, in 50th …

Neutral flow dynamics in Hall thrusters are not often regarded as a critical aspect that
controls thruster operation and discharge channel physics. This dissertation, combined with …

In order to model the non-equilibrium plasma within the discharge region of a Hall thruster,
the velocity distribution functions (VDFs) must be obtained accurately. A direct kinetic (DK) …

Hall thrusters are widely used as space electric propulsion devices. Due to the complex
plasma phenomenon and high computation cost, currently it is difficult to fully simulate the …

Grid-based kinetic models are promising in that the numerical noise inherent in particle-
based methods is essentially eliminated. Here, we call such grid-based techniques a direct …

The anode boundary layer in atmospheric pressure arc discharges is studied numerically on
the basis of the hydrodynamic (diffusion) equations for plasma components. The governing …
