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.

液氢强制流动传热的研究对大型高温超导磁体的冷却设计具有重要意义。为了研究液氢在大范围过冷度、流速和压力下的传热特性，研制了一套液氢热工水力学实验系统。为保证氢气安全，还建立了远程控制系统和联锁系统。利用该实验装置，对液氢池冷和强制流动冷却的稳态和瞬态传热特性进行了实验研究。此外，还研究了BSCCO和MgB2等高温超导线材在液氢中的冷却特性。
