摘要

A basic investigation directed towards the development of the dielectrophoretic oxygen converter has been conducted. The work has covered dielectrophoretic theory, application to design, supporting experiments, preliminary design of a 25-liter converter, and construction of a small dielectrophoretic tank for flight test experiments. We find that the level of the dielectrophoretic forces can be predicted quantitatively. These force levels are limited in a practical converter design by dielectric breakdown of the medium, by stability of the fluid-vapor interface, and sometimes by force wells that trap fluids in the vicinity of the electrodes. Criteria for converter design in view of these limitations are developed, and it is shown that in a 25-liter converter "equivalent dielectrophoretic gravity fields" in the region from 10-3 to 10-1go should be attainable on the fluid with a 20,000 volt potential. Provisions made for uninterrupted operation up to 25 g. Liquid-vapor separation occurs continuously in the converter. The entire converter, with auxiliaries, weighs 14.0 pounds dry.
