AEROSOL BEHAVIOR IN HIGH PRESSURE ENVIRONMENTS

Abstract

The purpose of this study was to elucidate hazards to personnel arising from aerosols in high pressure helium-oxygen atmospheres utilized in deep submergence vessels. Aerosol properties of sedimentation, diffusion, agglomeration, electrification, and the slip correction factor have been extrapolated to pressures of 500 psia. The effects of the atmosphere upon aerosol filtration, electrostatic deposition, condensation and evaporation have been considered. Experiments have been performed to verify the possibility of maintaining a corona discharge in the given atmosphere for both positive and negative applied potentials. The deposition patterns of aerosols within the lung have been considered via the application of a deposition model to a range of particle sizes and pressures. The possibility of significantly increased respiratory deposition is evident.
