Mathematical and Computational Issues in Plasma Microthrusters

Abstract

OXYGRNThis grant involved two different projects: The first one was focused on COIL flows and was performed during the first year. The second one was focused on micro-ppt thrusters. Specifically, the objectives of this grant were as follows: (1) Numerica study of unsteadiness effects in the Chemical Oxygen Iodine (COIL) experiment conducted at Air Force Labs (year 1 only). (2) Develop spectral/hp element algorithms for the multi-species, compressible, viscous MHD equations for non-equalibrium plasma microflows in the continuous and transitional regimes (years 1-3). (3) Apply algorithms to modeling and optimization of micro-plasma thruster (micro-PPTs) (year 2-3).
