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...

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...

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...

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...
