Computational modelling of water-fuelled Hall Effect Thrusters
Journal of Electric PropulsionAbstract This paper presents a Particle-In-Cell code designed for the simulation of water-fuelled Hall Effect Thrusters, including two different propellants: water vapour and oxygen (the latter being intended for water electrolysis propulsion with oxygen supplied through the anode and hydrogen through the cathode).

Investigation of the Arcjet near Field Plume Using Electrostatic Probes [PDF]
The near field plume of a 1 kW class arcjet thruster was investigated using electrostatic probes of various geometries. The electron number densities and temperatures were determined in a simulated hydrazine plume at axial distances between 3 cm (1.2 in.)
