Abstract

This paper examines outgassing kinetics in the air and purging flow environments, as well as including a comparison to full outgassing in vacuum. The experimental data and models reported in the literature on the material outgassing in those environments are examined and summarized. The models are used to examine evaporation of water and DC 200 silicone fluid and outgassing of representative spacecraft materials in the normal air, purging flow and vacuum environments. The models can be used to estimate the outgassing rates of materials under various conditions in those environments, by knowing the outgassing rate in one of those environments. The implication of study results to spacecraft contamination control is also addressed.
