LeRC reduced gravity fluid management technology program

The program reviewed in the present paper has provided information of the reduced-gravity behavior of fluids, thermal control of cryogenic tankage, and fluid management system design. The studies are currently shifting from the utilization of in-house experimental facilities to the development of Spacelab experiments. The cryogenic fluid management experiment, currently undergoing detailed design, is expected to provide an orbital evaluation of a subcritical liquid hydrogen storage and supply system, as part of the Shuttle/Spacelab program. Efforts are continuing to develop computer techniques for simulating reduced-gravity fluid dynamic processes.
