Computer Modeling and Optimization of OBOGS with Contaminants

Abstract

This report covers the second year of project dealing with the development of an OBOGS computer model to aid in design specification of these oxygen generation systems for the Army's in-flight, medivac, and field hospital use. A simple three component model using uncoupled linear isotherms has been developed but not yet tested due to a lack of data. Also, the two component model for oxygen-nitrogen has been modified to include a power law correlation for the parameters in the isotherm expressions. While this correlation is entirely empirical, it improves performance of the model at low temperatures. A major change in the project has been the transfer of the experimental duties from USAARL to UT. A preliminary set of isotherm experiments has been done (using available equipment at Brooks Air Force Base) and equipment has been ordered for the experiments to be done here at UT. The model is currently being rewritten and generalized for three components with general isotherms using a new equilibrium model. Keywords: Aeromedical; Oxygen concentrators; Molecular sieve.
