Poster Presentation
Knowledge of film boiling heat transfer from a heated wire to forced flow of liquid hydrogen or liquid nitrogen in a narrow gap is important for conductor design and quench analysis of superconducting magnets wound with high-Tc cable in conduit conductor (CICC). However there have been few experimental data as far as we know.
Film boiling heat transfer coefficients in liquid hydrogen were...

CEC-12 - Fluid Mechanics, Heat Transfer, and Cryogen Properties
Poster Presentation
The knowledge of forced flow heat transfer of low temperature hydrogen under supercritical pressure is important for designing superconducting magnets wound with cable in conduit conductor.
Forced flow heat transfer of hydrogen from a round wire in a vertically-mounted pipe was measured at the pressure of 1.5 MPa and the temperature of 21 K by applying electrical current to give an...

Wall-type heat exchanger(WTHX) and Fin-type heat exchanger(FTHX) are attached to the first and second stage cold head of two G-M crycoolers respectively in the simulating experimental platform of the internal purifier(SEPEIP). WTHX and FTHX play a significant role in SEPEIP, WTHX is designed to remove heat from helium and freeze-out extremely few impurities, FTHX is for further cooling the...

Poster Presentation
Liquid hydrogen has been used as a fuel for a rocket engine and moderator material for cold neutron source. Recently, it is expected as a coolant for high-Tc superconducting devices because of its excellent cooling properties. The knowledge of transient heat transfer in forced flow of liquid hydrogen is necessary for the cooling design. However, there have been no experimental data on the...
