| Research Abstract |
The knowledge of forced flow heat transfer in liquid hydrogen is important for cooling design of large scale HTS superconducting magnets. An experimental system for thermal hydraulics of liquid hydrogen has been developed, designed and made in order to investigate the heat transfer characteristics for wide ranges of subcoolings, flow velocities, and pressures up to supercritical. The remote control systems and the interlock systems were also established for hydrogen safety. By use of the experimental set-up, steady state and transient heat transfer characteristics in pool cooling and forced flow cooling of liquid hydrogen were investigated experimentally. Additionally, cooling characteristics of High Tc wires, such as BSCCO and MgB2, immersed in liquid hydrogen were investigated.
