  1. 367. Applications of Ortho-Para Hydrogen Catalyst
    GLEN MCINTOSH (MCINTOSH CRYOGENICS LLC)
    30/06/2015, 16:00
    CEC-01 - Large-Scale Refrigeration and Liquefaction
    Contributed Oral Presentation
    The underlying theory of hydrogen Ortho-Para conversion has long been known, but the specifics of non-linear heat of conversion from normal to para hydrogen have not been widely disseminated in the cryogenic literature. These factors are reviewed and thermally efficient applications in liquefiers and back conversion cooling systems are illustrated.

  2. 375. Modification of liquid hydrogen tank for integrated refrigeration and storage
    Adam Swanger (NASA Kennedy Space Center)
    30/06/2015, 16:15
    CEC-01 - Large-Scale Refrigeration and Liquefaction
    Contributed Oral Presentation
    The modification and outfitting of a 125,000-liter liquid hydrogen tank was performed to provide integrated refrigeration and storage capability. These functions include zero boiloff, liquefaction, and densification and therefore requires provisions for sub-atmospheric tank pressures within the vacuum-jacketed, multilayer insulated tank. The primary structural modification was to add...

  3. 469. Ground Operations Demonstration Unit for Liquid Hydrogen Initial Test Results
    Bill Notardonato (NASA Kennedy Space Center)
    30/06/2015, 16:30
    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Contributed Oral Presentation
    NASA operations for handling cryogens in ground support equipment have not changed substantially in 50 years, despite major technology advances in the field of cryogenics. NASA loses approximately 50% of the hydrogen purchased because of a continuous heat leak into ground and flight vessels, transient chill down of warm cryogenic equipment, liquid bleeds, and vent losses. NASA Kennedy Space...

  4. 355. Spallation Target Cryogenic Cooling Design Challenges at The European Spallation Source
    John Jurns (European Spallation Source ESS AB)
    30/06/2015, 16:45
    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Contributed Oral Presentation
    The European Spallation Source (ESS) project is a neutron spallation source research facility currently being designed and built outside of Lund, Sweden. A linear accelerator delivers a 5 MW, 2.0 GeV, 62.5 mA proton beam to a spallation target to generate fast neutrons. Supercritical hydrogen circulates through two moderators surrounding the target, and transforms the fast neutrons emitted...

  5. 373. Total Hydrocarbon Accumulation in Liquid Oxygen Storage Systems
    Dr Barry Meneghelli (VENCORE - Kennedy Space Center)
    30/06/2015, 17:00
    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Contributed Oral Presentation
    Rocket propulsion testing depends, to a large extent, on the quality of liquid oxygen to ensure reliable system performance. Impurities within liquid oxygen may not only degrade test article combustion performance, but in sufficiently high concentrations could react with oxygen or cause an ignition in facility systems. Combustible contaminants in liquid oxygen can be classified as “total...

  6. 386. Simulated Propellant Loading System: Testbed for Cryogenic Component and Control Systems Research & Development
    Jaime Toro Medina (NASA Kennedy Space Center)
    30/06/2015, 17:15
    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Contributed Oral Presentation
    Technologies in the fields of cryogenic components and control systems is constantly evolving to advance the state of current cryogenic operations that will support future space exploration missions. To meet new demanding requirements, these missions will increasingly rely upon research and development in energy-efficient storage, transfer and use of cryogens and cryogenic propellants on Earth...
