Experiment, Modeling, and Simulation of Advanced Materials - Plasma Interactions in the Space Environment
Abstract
The objective of this proposal is to mitigate create and investigate multispecies plasmas existing plasma and thruster models that do not capture the inherent dynamic time-varying nature of the systems, by comparing and assessing different modeling approaches in capturing true system dynamics by techniques such as time-lag phase portrait for plasma and propulsion systems. Of particular focus in this work is to create multi-species helium-argon plasma mixtures in a multipole plasma cell, and measure charged particle densities and temperature for different mixture total pressure and species partial pressures the sheath physics for multi-species plasmas consisting of chemically reacting species, such as air, N2, N2-H2 mixtures, and CO2-H2O-N2 mixtures representative of the decomposition products of chemical monopropellants.
