The resupply of the cryogenic propellants is an enabling technology for space-based orbit transfer vehicles. As part of NASA Lewis's ongoing efforts in microgravity fluid management, thermodynamic analyses and subscale modeling techniques have been developed to support an on-orbit test bed for cryogenic fluid management technologies. Analytical results have shown that subscale experimental modeling of liquid resupply can be used to validate analytical models when the appropriate 'target' temperature is selected to relate the model to its prototype system. Further analysis have been used to develop a thermodynamic model of the tank chilldown process which is required prior to the no-vent fill operation. These efforts have been incorporated into two FORTRAN programs which have been used to present preliminary analytical results.
