  1. 140. Design of a heater for the CSNS cryogenic hydrogen system
    Ms Yu Zhang (Institute of High Energy Physics, CAS)
    09/07/2014, 14:15
    C-06: Heat transfer and thermo-physical properties of solids and fluids
    Poster presentation (105min)
    The China Spallation Neutron Source consists of a pulsed neutron source with ~20 K and 1.5 MPa supercritical hydrogen used as moderator. The dynamic heat load due to the neutron moderating is removed by the circulation of cryogenic hydrogen. A pulsed dynamic heat load is induced by the intense pulsed proton beam injection and trip, and a large pressure fluctuation in supercritical hydrogen...

  2. 106. Effective Temperature of Non-uniform Temperature Distribution and Size Effects of Effective Temperature
    Dr Woo Kang Kim (Institute for Basic Science)
    09/07/2014, 14:15
    C-06: Heat transfer and thermo-physical properties of solids and fluids
    Poster presentation (105min)
    The thermal radiation properties from a non-uniform temperature distribution are investigated and the effective temperature for non-uniform distribution is defined. The thermal radiation spectra for non-uniform temperature distributions are shown as a function of frequency and are compared to the effective temperature. The thermal radiation from arbitrary size of particle is derived and the...

  3. 22. Heat transfer simulation to liquid nitrogen from HTS tapes at current overloads
    Dr Vasilii zubko (VNIIKP)

    C-06: Heat transfer and thermo-physical properties of solids and fluids
    Poster presentation (105min)
    Knowledge of HTS materials behavior at overload currents is important to design fault current limiters or fault protection systems of electro-technical devices. Recently we observed sharp voltage peaks during rectangular current pulses on HTS tapes cooled by boiling liquid nitrogen. We explain these peaks by analysis of transient cooling regimes in liquid nitrogen. It is common knowledge that...

  4. 375. Investigation on the thermal equilibrium around a cryogenic accidental event and the impact on the possibly enclosed surrounding environment
    Mr Ketan CHOUKEKAR (ITER-India (Institute for Plasma Research))
    09/07/2014, 14:15
    C-06: Heat transfer and thermo-physical properties of solids and fluids
    Poster presentation (105min)
    Complex and large cryogenic distribution systems are an integral part of a fusion machine having superconducting magnets, cryopumps etc. The various equipment of the cryogenic distribution system are interconnected via notably large cryogenic transfer lines (CTL) to distribute the cold helium to the end users. During the nominal operation of the fusion machine, the helium inventory in the CTLs...
