A Hydrophobic-Hydrophilic Zero Gravity Liquid Gas Phase Separator

A number of zero-gravity liquid-gas phase separators such as rotating units, elbow type units, porous plate, and the hydrophobic-hydraulic type discussed in this paper are presently being developed for spacecraft use. The basic theory of this unit is presented and the application of surface tension phenomenon is discussed as they apply to the design. The materials of construction are covered, and the ultimate use on Apollo 11 is described.
