    Poster

    With the global focus on energy and environmental issues, hydrogen energy development has become more and more important. The liquid hydrogen pump is an important equipment for hydrogen transportation, whose performance is significantly decided by the impeller. In this paper, we designed an integrated impeller with an inducer and an centrifugal impeller and optimized the axial length and...

    Poster

    Liquid hydrogen piston pump is the key equipment in the process of storage, transportation and refueling of liquid hydrogen. The timely motions of suction and discharge valves are beneficial to the transport performance and volumetric efficiency of the pump. This paper sets up an operation frame of liquid hydrogen piston pump in which reciprocating piston and check valves with conical spool...

  3. 150. C1Po2C-03: Theoretical power consumption analysis of pressurization process of reciprocating liquid hydrogen piston pump
    Ming He (Technical Institute of Physics and Chemistry)
    10/07/2023, 14:00
    Poster

    Compared with other off-site hydrogen refueling stations, the liquid hydrogen refueling stations have the advantages of high storage and transportation efficiency, good economy of medium and long-distance transportation, low construction investment and high hydrogen purity, which has become an inevitable trend in the development of hydrogen refueling stations in the future. The energy...

  4. 143. C1Po2C-04: Development of a dual flow transfer system with a centrifugal pump for liquid helium
    Johannes Doll (TU Dresden)
    10/07/2023, 14:00
    Poster

    At research institutes, liquid helium is commonly transferred to mobile dewar vessels via a single flow transfer line, driven by a pressure built up in the storage vessel. In this process, a considerable amount of the liquid evaporates according to the prevailing pressure drop and due to the heat leak into the transfer line. Further, the generated flash gas must undergo an energy intensive...

  5. 419. C1Po2C-05: Performance modeling and test of an electrical induction motor at cryogenic temperature
    Aaron Chick (Barber-Nichols, LLC)
    10/07/2023, 14:00
    Poster

    Barber-Nichols has significant experience successfully applying induction motors in cryogenic fluid pumping applications between 100 and 4.2 Kelvin. These induction motors typically include metallic materials of silicon steel laminations, aluminum rotor bars, and copper windings. Barber-Nichols recently validated an analytical model for induction motor performance with dynamometer testing at...

  6. 578. C1Po2C-06: Numerical analysis of the performance of the inlet valve in a liquid hydrogen pump
    Dr Shaoqi Yang (Technical Institute of Physics and Chemistry, Chinese Academy of Sciences)
    10/07/2023, 14:00
    Poster

    Excessive pressure drop will cause the liquid hydrogen vaporing when the liquid hydrogen flows through the inlet valve, resulting in a decrease in the volumetric efficiency of the reciprocating pump. In this paper, we will optimize the structure and inlet parameters of the inlet valve through numerical simulation to reduce the vaporization rate and improve the volumetric efficiency of the...
