This activity will build upon the existing Spacecraft Plasma Interaction System developed since more than 10 years under ESA and CNES funding and especially the latest development allowing the modelling of plasma plumes / spacecraft interactions. This activity will target the modelling of droplets generated from liquid based electrical thrusters, droplet evolution after emission (e.g. charge state, evaporation), interaction processes with the environment (ambient ionisation), deposition and interaction with s/c surfaces in order to provide a full diagnostic package for mission preparation and in-flight analysis. In addition molecular contamination models will be tested against actual data and refined such as to incorporate droplet generated materials. An analysis of numerical performances for multiple thrusters and contamination simulations on full scale spacecraft will be carried out and an improved numericalscheme proposed and possibly implemented in order to increase the code usability towards full scale / complex systems.
