A Model to Describe Oil Loss Under Vacuum Conditions.

Abstract

A computer model of oil loss under vacuum conditions has been generated. The model is based on empirically determined vapor pressures and, thus, loss rates of a homologous series of straight-chain hydrocarbons. Several hypothetical oil distributions, i.e., component percentages vs molecular weights, are discussed in terms of bulk vapor pressure and oil loss. The use of the vapor pressure of unused oil to calculate oil loss rates is shown to be inappropriate. Lubricants, Space Environment, Modeling, Vacuum, Oils, Vapor Pressure.
