Computer Modeling and Optimization of OBOGS with Contaminants
Abstract
The ultimate goal of this is to insure proper design of molecular sieve oxygen generation systems for the US Army's in-flight, medivac, and field hospital use. Specifically the research involves further development of an OBOGS model to include the effects of contaminants in the feed air. This OBOGS model can be used to optimize and design OBOGS systems with respect to system parameters such as cycle time and bed and valve dimensions. A three component feed OBOGS model has been developed. The model uses a linear oxygen isotherm and Langmuir type isotherms for nitrogen and the contaminant; the isotherms are uncoupled. The model assumes plug flow, isothermal conditions, and uses a common mass transfer coefficient (linear driving force) for all components. Radial gradients and intraparticle gradients are ignored. The model is expected to work best for contaminants that are relatively small and non-polar, so that mass transfer resistance is small.
